Compress images to under 500 KB, a common limit for documents, forms and email. Photos keep their detail and full size in most cases, at a much smaller file size.
Your images never leave your device. No sign-up, no watermark.
What fits in 500 KB
We ran this exact compressor on four test images with the target set to 500 KB. This is the pixel size each one came out at, so you know what to expect before you start:
| Test image | As JPG | As WebP | Result |
|---|---|---|---|
| Group photo, 1920 × 1280 | 1920 × 1280 | 1920 × 1280 | full size, sharp on any screen |
| Portrait, 1920 × 1350 | 1920 × 1350 | 1920 × 1350 | full size, sharp on any screen |
| Group of four, 1920 × 1537 | 1920 × 1537 | 1920 × 1537 | full size, sharp on any screen |
| A4 text page, 1654 × 2339 | 1654 × 2339 | 1654 × 2339 | readable, even small print |
When you need an image under 500 KB
- Upload limits of 500 KB for photos and documents on application sites.
- Large website images that still need to load quickly.
- Emailing several photos in one message.
Tips for a sharp 500 KB image
Use the before and after slider to compare the result with your original. At 500 KB you should not see any difference on a normal screen.
Check the form’s other rules too. If it asks for an exact pixel size, use the Image Resizer first; for a passport or visa photo, start with the Passport Photo Maker.
Questions
Is 500 KB the same as 0.5 MB?
Yes. The tool counts 1 KB as 1000 bytes, so the file also fits forms that count 1 KB as 1024 bytes.
Will the file be exactly 500 KB?
It will be just under 500 KB, never over, so upload forms accept it. The tool counts 1 KB as 1000 bytes, which also keeps it under the limit on forms that count 1 KB as 1024 bytes.
Is my image uploaded anywhere?
No. The compression runs in your own browser, so your photo never leaves your device. It works on phones and computers, with no sign-up and no watermark.
Which files can I use?
JPG, PNG, WebP and iPhone HEIC photos. PNG files are saved as JPG when you compress to a size, because PNG can’t be made small enough for most limits.
