- I do not quite understand. Are you adding more layers to the file, but yet the number of layers is the same? What is in those layers?Rafael– Rafael2024-09-13 16:26:14 +00:00Commented Sep 13, 2024 at 16:26
- @Rafael I add more layers to the PSD but they are not toggled to visible when saving to PNG, so my understanding is that if the layers aren't visible they won't affect the final file, but they are. A file with 3 visible layers is 1.5MB, but the same file with an addition of 200+ non-visible layers is now 1.7MB.formicini– formicini2024-09-13 16:58:12 +00:00Commented Sep 13, 2024 at 16:58
- 1All the answers given so far are (more or less) speculative, because that's all they can be with the information you've provided. To determine the real cause of the phenomenon you've observed, you may need to show us some of these PNG files. Preferably two that look the same but have different sizes. Someone could then analyze the contents of the files and see what's making one of them bigger than the other.Ilmari Karonen– Ilmari Karonen2024-09-14 08:27:07 +00:00Commented Sep 14, 2024 at 8:27
- @IlmariKaronen Any two PNGs with the same dimensions, but containing different images will most likely have different file sizes. This is a fact, not speculation. If they were the same, it would be mere coincidence. The OPs expectation seems to be that two PNGs with the same dimensions should have the same file size, which is simply not true. The difference in file size is caused by the lossless compression used in the PNG format itself. Nothing really to do with Photoshop or layers. This is really just a red herring. Correlation is not causation. The same thing happens in GIMP.Billy Kerr– Billy Kerr2024-09-14 11:21:00 +00:00Commented Sep 14, 2024 at 11:21
- I didn't know this isn't a commonly known issue, sorry everyone. I have included my working file in the question, if you could please check to see if there's anything wrong with it that will be great.formicini– formicini2024-09-14 16:29:43 +00:00Commented Sep 14, 2024 at 16:29

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. adobe-illustrator), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
