PRACTICAL GUIDE
How to reduce photo file size
Learn how to compress photos toward 100KB, 500KB, or 1MB for email and upload limits, then compare the downloaded result for usable clarity.
Before you begin
Decide where the photo will be used. Document photos must keep text readable, while a messenger or profile image may benefit more from a small size. Keep the original separately before comparing results.
Step-by-step
- Add JPG, PNG, WebP, or supported image files.
- Choose a target such as 100KB, 300KB, or 500KB, or use the recommended setting.
- Check result size and reduction, then download the files you need.
Check the result before sharing
For document photos, zoom in on small text and stamps. For portraits, check that faces are not heavily blocky. When downloading several files, extract the ZIP and confirm file names and count.

Will PNG always shrink a lot?
PNG behaves differently from photo JPG because it is often used for transparent backgrounds or simple colors.
What if the output is too blurry?
Try a larger target size or lighter compression and compare the result with the original at zoom.
About this guide
This page explains a practical file-handling workflow. Keep an original copy of important files and review the downloaded output before submitting it to a third party.

Check the upload limit before reducing a photo
The best way to reduce a photo depends on the required file limit. Start on a dedicated page when the limit is exact, such as 100KB. When there is no fixed limit, use the general compressor and compare file size with readable detail.
