Choose filesCompress an image to 50KB (or any size limit)
Many websites, job portals and forms reject uploads above a set size, and 50 KB is one of the most common limits. This tool shrinks your image until it fits. It lowers the quality only as much as needed, and if the image is still too big it can also reduce the pixel size a little. You see the real result before you download.
The same tool handles other limits too. Tap another size in the settings, or type your own number. Some portals also have a minimum size, so check the rules before you compress too far.
What next? Need a different format afterwards? Use the image converter. Want to compress many photos at once for your website? Open the image compressor.

50 KB limits and how to hit them
50 KB is a very tight cap. These combinations usually work. Always check the exact rules of the page you are uploading to.
| What you are uploading | Recommended format | Tip |
|---|---|---|
| Signature or stamp (small scan) | PNG or JPG | Crop tight to the ink, then compress. Signatures fit easily. |
| ID / passport photo | JPG | Keep dimensions around 400×500 px. PNG rarely fits. |
| Profile photo for a portal | JPG or WebP | A 600×600 px JPG at quality ~70 usually lands under 50 KB. |
| Scanned document page | JPG | Use grayscale and reduce dimensions if needed. |
What you get with the compress image to 50kb
Finds the best quality that fits
Instead of guessing a quality value, the tool searches for the highest quality under your limit.
Reduces dimensions only if needed
If quality alone can’t reach the limit, the image is scaled down just enough. Turn this off to keep the exact pixel size.
JPG, PNG, WebP and more
Pick the format your form requires. For the smallest result on photos, JPG or WebP works best.
Bulk processing
Add up to 30 images at once, then download one, several or all of them as a ZIP file.
Undo and apply to all
Made a mistake? Undo it. Happy with your settings? Apply them to every image with one click.

Frequently asked questions
+How do I compress an image to 50KB?
Drop your image on this page. The 50 KB limit is already set, so it is compressed automatically and you see the final size. Then click Download.
+Will my image look bad under 50KB?
For signatures, stamps and small profile photos, no. For large detailed photos, the tool has to lower quality and may reduce dimensions — the result shows exactly what you get.
+Can I compress a PNG to 50KB?
Yes, but PNG often needs fewer colors or smaller dimensions to fit. For photos, JPG or WebP gives a much better result at this size.
+Why is my file still over 50KB?
Some images can’t reach 50 KB without visible damage. Allow the tool to reduce dimensions, or crop the image tighter first.
+What pixel size is 50KB?
There is no fixed answer — it depends on the content. A simple signature can be 200×100 px, while a detailed photo may need to be under 600 px wide.
+Is my image uploaded anywhere?
No. Compression runs in your browser, so your image never leaves your device.
