Compress Image to 50 KB
Get your photo under 50 KB in seconds, with the best possible quality. Perfect for passport photos, ID photos and online application forms.
We search for the highest quality that fits under your limit and only reduce the dimensions when quality alone is not enough. 1 KB = 1,000 bytes, so the result also fits limits that use 1,024.
Auto saves JPG (accepted by every form and website), or WEBP when you upload WEBP.
How to use Compress Image to 50 KB
- 1

- 2

The target is already set to 50 KB. You can change it any time or add maximum pixel dimensions.
- 3
Download
Compare before and after, then download the image or all images as a ZIP.
Reduce image size to 50 KB
Passport, visa and exam portals commonly require photos between 20 KB and 50 KB. This tool compresses your image to 50 KB or less while keeping it as sharp as possible. It finds the highest JPEG quality that fits and only reduces the pixel dimensions when needed.
Why your image is rejected
Phone cameras save photos of 2–10 MB, far more than most forms allow. Uploading a file that is even 1 KB over the limit is rejected, so the result is always kept safely under 50 KB, counting 1 KB as 1,000 bytes so it also passes limits that use 1,024 bytes.
Tips for 50 KB images
- Crop away empty space first with the Crop tool, so more of the file size goes to the important part.
- If the form requires exact pixel dimensions, enter them as the maximum width and height.
- Need print sizes in cm or inches? Use Resize Image in cm.
- Need a different limit? The main Compress Image to Size tool accepts any value in KB or MB.
