Open Compress Image here and it is already set to fit a picture within 50 KB. Add one file, and the tool tries a series of JPEG qualities, keeping the best one that stays under the limit. The work is done by your browser, so the image is never uploaded. It suits portraits, scans of documents, and simple graphics.

Result
Your compressed image(s) will appear here, ready to download.
When you need a file under 50 KB
- An online form has a photo field with a strict small limit, and your phone picture is many times too large.
- You want to attach a scanned certificate or ID page to an application, and the upload box refuses files above a few dozen kilobytes.
- A messaging app compresses your picture in a way you cannot control, so you prefer to prepare a small copy yourself first.
- A profile image needs to load quickly on a page, and a light file keeps it from slowing things down.
What to expect
- 50 KB is achievable for a moderately sized portrait or a cropped scan, but a full-resolution camera photo often needs resizing as well.
- Output is a JPEG. If your source is a PNG screenshot with flat colors, the JPEG version can show fringing around text.
- A source with real transparency is not modified, since converting it would lose the see-through areas.
- The tool does not shrink the dimensions, only the quality, so very large pixel counts make the target harder. The Resize Image tool on this site is the right first step in that case.
How to use Compress Image to 50 KB
Add one image. Drop a single image onto the upload area or choose it from your device. Fit to a target size works on one image at a time.
Check the mode. Fit to a target size is already selected. Switch to Compression level for Low, Medium or High.
Check the target. 50 KB (50 KB) is already entered in Target size. Change it if you need a different size.
Fit the image. Select Fit image to size and wait for the progress bar to finish.
Download the result. Compare the sizes and download the JPEG. If the target was missed you are told.
Limits and privacy
- One image at a time in this mode, up to 25 MB.
- Output is always JPEG, so PNG and WebP inputs are re-encoded as JPG.
- An image with real transparency is left untouched, because JPEG cannot store transparency.
- If the target cannot be reached you get the smallest result the tool can make, marked as missing the target.
- The file is processed in your browser and is not uploaded.
- Without an account you get 3 free actions on this tool every 24 hours; signing in removes the cap.
Frequently asked questions
What if my file is still bigger than 50 KB?
The tool will say the target was not met and hand you the smallest JPEG it produced. A very high pixel count is the common reason, so reduce the width and height with Resize Image and try again.
Is the quality search exact?
It is a short, bounded search, not an exhaustive one. It measures real file sizes at each attempt and keeps the best quality that fits, which may leave a little unused room under the limit.
Will a screenshot with text stay readable?
Usually, if it is not huge, though small text can pick up halos at lower quality. Check the preview before you use the file.
Does it change the image's width and height?
No, only the encoding quality changes, so the picture keeps the same dimensions as the original.
