How to compress an image to 50KB
Quick answer: upload the image, leave the target at 50 KB and press Compress. You get a JPG that is 50 KB or less, with the best quality that fits. Works for photos, signatures and scanned documents.
- Add the image you need to upload.
- Keep 50 KB as the target (or type a different limit).
- Compress and download.
Common 50 KB requirements
- Applicant photos on many government and bank job portals.
- Signature uploads (often 10–50 KB).
- School, college and exam registration forms.
Getting the best result at 50 KB
- Crop first. Remove empty background with the crop tool so the 50 KB is spent on what matters — your face or your signature.
- Resize to the size the form asks for. A 600 × 600 px photo fits 50 KB easily at high quality; a 4000 × 3000 px photo does not. Use the resizer.
- Signatures: sign with a dark pen on white paper and photograph it in good light for a clean, small file.
