Whe OCR is enabled and a PDF with imported images is saved, the resulting PDF is searchable and text can be copied out of it, but for that you have to right click in Adobe reader and choose the select tool. With that you can select the text withing the PDF and copy it to clipboards. On the other hand there is PDFGear that can save an imported PDF into TXT.

If you're comfortable using a command line, you can just use tesseract directly for this use case rather than trying to do it through NAPS2.

I have thousands of png files taken from family history websites. I would like to be able to just copy the text, and then paste into my database. For some reason OCRing just a sample of 10 png's does not seem to do anything, and nothing tells me if anything has happened, or even if its finished. All i need is the ocr to be outputed into txt files. I however managed to get all png's into 1 pdf and also individual pdf's generated. I do not like copying text from off pdf, as they tend to be very table...
-
Why do you need a TXT file? Check the documentation here: https://www.naps2.com/doc/ocr
-
Sorry - my brain sometimes thinks everyone knows what I am thinking. Yes OCR as well. Import or drag and drop files or a directory. Not sure if each png file would then have its txt file saved seperatly into the same directory as the png?
-
You did not say if you want to do OCR too, but try to open NAPS2 and drag and drop the images into it. Or use the IMPORT menu button.
-
How to convert prescanned png's into pdf or txt ? Just cannot find a method of how to do this. Any ideas please.

The problem is solved! NAPS does not correctly interpret the registry parameter HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences\MaximumAttachmentSize If it's set to 0, it means that there is no size limit for OUTLOOK, and the maximum size for NAPS is 0! Therefore, we set 1024000 in the decimal system and enjoy life! reg add "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences" /v "MaximumAttachmentSize" /t REG_DWORD /d "1024000" /f

I have been trying to install the program on my MacBook Pro running High Sierra (10.13.6), but the installer says I need 10.15 or higher. I tried a few older versions, but they so far have the same limit. So I was wanting to know what is the most recent version that supports macOS 10.13? Thanks in advance.

Using the command line option -o, I noticed that the program did not like file names over 18+ characters. It would create up to the 18 character name and then stop. Create a 0 byte file. If I kept the name under 18 characters it would save the file no problem.

You can premap a network drive. Use the command line with an -o \networkshare or the mapped drive letter

hi, i would like to suggest adding a "page size" option (e.g., force a4) to the pdf settings window . currently, when merging pdfs of different sizes or importing high-res jpgs, the resulting document has inconsistent page dimensions. having a dropdown menu here to select a standard output size (like A4) and an option to "srink to fit" would be a huge improvement for document standardization. this would be a huge help when merging different files or importing high-res photos. thanks for considering...

Hi, tremendous product here, and I'm really enjoying the remote scanner capability, phenomenal addition there! There is only one thing I still use Adobe for is to add pages to an existing PDF, where that PDF is password-protected. You see, I have quite a few password protected documents (different passwords), and can't figure out how to save updated documents while preserving the existing password. I know I can add it again, but it would be great if it were an option I could enable, especially with...

I want to share a problem I am having. I am running NAPS2 version 8.2.1.0 on Win10 64bit. I use Kodak Scanmate i1180 via USB and TWAIN. I scan 5 pages of documents (10 sides) at a time, using a combination of greyscales and B/W at 300dpi. All pages appear clearly on the NAPS2 window. I then save to PDF with OCR enabled. I use Foxit Reader to view the files. Every now and then, Foxit will not read some of the PDFs thus created. Opening them in PDF24 Creator will show 3 visible pages, and 7 blank pages....

I think I figured out a solution.... I just need to put the document on the scanner facing backwards.
-
Just started using this wonderful software. I know this must be a setting somewhere, but I can not find it. I have a Neat ND-1000 duplex scanner. I figured out how to get a file to save, removing blank pages. The only issue is that the file has the pages in reverse order. So the first page of the document is the last page of the scanned file.
-
It sounds like you're talking about the UI provided by your scanner manufacturer, which has nothing to do with NAPS2. In your NAPS2 profile settings you should be able to select "Use predefined settings" instead of "Use native UI" to skip it, but otherwise it's based on your scanner's driver.

8.2.1.0 the F2, F3, etc. keyboard shortcut doesn't seem to work when the scan dialogue window is up. I need something that will change/fix the scan profile(not just the device but the particular scan setting) into one and stay that way throughout a multiple-page scan session... But if I try to use something different than a default setting, then when a single scan is done and i scan again, the setting that shows up is the default, not the last used one. Is there a way to change the default setting...
-
What NAPS2 version are you using? I do remember something that once upon a time an old version had such bug. Other than that, you can use Keyboard Shortcuts. Each scan profile can be invoked via F2, F3, F4 etc. This is the fastest way to handle this.
-
How do you change the default scan profile(not the device profile) during a session? Currently, each time I do a scan, it always defaults to a default profile, which is grayscale for me. If I want to do a color scan for several pages, it seems that for each page i have to reselect the color scan setting. Is there a way to change the default scan profile for a particular session or have the scan menu to default to the last scan profile used?

OOPS - I didn't click on the page. Then I had acccess to the image menu. THANKS! Old: I set the scanner to greyscale and scanned. The image icon at the top was greyed out. Is that the image menu you mentioned? If I change the left side from Greyscale to Black & white, I don't see a window to change white / black threshold.
-
You'll need to click the image to select it, then you can use the menu.

You can also try "Document Correction" under the Image menu.
-
I think that it is all about the drivers and the post processing of the scanned document. Did you check for a more recent driver? Also, is there a more recent firmware update for the Epson printer?

I'm testing naps2 and found one strange bug: when scanning b/w documents (printed previously by laser printer on common office paper), background in scanned images is not white, but rather "blue-ish". When I change color settings to b/w, background is "grey". No matter what I try with settings, it is still the same. But when I use original app, scanned documents look much better, with nearly white background (printer/scanner epson xp-830). How could I fix this?

Thomas Moeller posted a comment on discussion General Discussion
The scanner is not recognised. I have the firmware file 1300_0C26.nal. Where do I have to put it so NAPS2 will use it? It should show up in the SANE section in NAPS2.
-
You can also scan in either color or grayscale, then after the scan, under the "Image" menu, click "Black and White" to convert to pure black & white for a small file size. This window will let you pick the exact white/black threshold and preview the results to make sure it's right.
-
That's because you are scanning in Black and white mode and not in gray scale. There is always some compromise as the scanner has to use some kind of threshold where it decides to show the pixel or not. Try gray scale.

I am using NAPS2 with a Brother MFC-L2700DW scanner. I want to scan tax documents - black text on a white background. But I get speckles / dots in white areas. Yes, the glass is clean. And if I do a color image, I don;t get the dots - but do get a much larger file size. Sometimes there's text on the back of the page that I think is 'tricking' it. Is there a way to set things so it knows - really dark area is black. lighter areas are all white? ie how to make monochrome scans crisper? Black text and...

I'm sorry, but no, that doesn't help. I didn't notice the Use native UI button before, so I tried it. "Native UI" leads me to expect the UI (and the controls) I get when I configure the scanner through its own software, but I don't get that. The UI looks the same as when the Use predefined settings button is selected. The initial dialog is the same except that Use native UI disables the Brightness and Contrast controls. I haven't tried to compare the Advanced dialog with and without Use native UI,...

Hi Jonathan, You should be able to click the pencil button to open the profile settings and select the "Use Native UI" radio button instead of "Use predefined settings" to get the Brother TWAIN/WIA/whatever interface to appear; and allow you to scan in duplex like you would in any other windows program if you have the Brother scanner driver installed. I believe they removed the native scan interface from the manufacturer and are using a standard one in the program for all scanners to make things...

I came here to report the same problem, and found this ticket instead. I edited my profile to specify the TWAIN interface, however, and I still see no duplex option. There's a "Flip back sides of duplex pages" option, but no way to select duplex in order for it to matter. I'm running Windows 11 Enterprise. NAPS2 is v8.2.1.0. My device is a Brother MFC-J6540DW. I'll check back in a few days, and if there's no response, it won't matter. I need a utility that can scan duplex now. NAPS2 is the most highly...

Try to install and then use the Twain driver. The via drivers may not have all the features implemented.

Hello, Naps2 (8.2.1.0) works almost perfectly on my W11 PC. I only have one problem : I have only one profile, with 500 PPP. In the main window, I also typed 500. Scanned image stays with 300. I tried with mac quality in the profile, no change. I don't understand what the problem is. BTW printer is a Brother MFC-J4340DW using WIA.

Hi, When running NAPS via the CLI, is there any argument I can use alongside --noprofile in order to flip duplexed pages? Just curious if this setting was only available via creating a profile and then specifying that profile in the CLI. Thanks in advance.

Hi all, Using a Neat ND-1000 I can get scans into NAPS2. But they come in backwards if I auto-save to PDF. Feature request: Add a "Reverse Order?" checkbox option in the profile under Auto-Save. *Expected behavior mimics a manual Reorder->Reverse All(N) operation in the app. *
-
Hi all. Just installed NAPS2 after a PC switch and realizing that Neat has basically abandoned the ND-1000 ADF scanner unless I pay $150 for their cloud warez. Good times... Bump on the request for double-sided ADF. I know I can do an interleave in the reorder tool, so this helps.

I have the same issue. NAPS2 does not always crash, but quite often. It happens when saving a scanned document as PDF file.
