Compress Image to 50KB Online
Some portals — signature uploads, profile thumbnails, visa forms — demand files under 50KB. Drag your image in, lower the quality slider until the live size counter drops below 50KB, and download. Processing is 100% local, so even sensitive documents stay on your device.
Live KB counter updates with every quality adjustment.
Resizing to 400–600px width plus 60% quality reliably lands most photos under 50KB.
Zero uploads — safe for signatures, IDs, and legal documents.
Frequently Asked Questions
How do I get an image under 50KB?
Combine two levers: reduce the quality slider to 50–65% and, for large photos, use a smaller output width. The live size readout confirms when you are below 50KB before you download.
Will a 50KB image look blurry?
For display sizes under 600px wide, a 50KB JPG is usually indistinguishable from the original. Tiny signature images at 50KB look perfectly crisp.
