Image Compressor
Compress JPG, PNG and WebP images to an exact target size — 20KB, 50KB, 100KB or any size you need — right in your browser.
About the Image Compressor
This free image compressor reduces JPG, PNG and WebP file sizes directly in your browser — your photos are never uploaded to any server, so private documents, ID photos and personal pictures stay on your device. Pick an exact target size like 20 KB, 50 KB, 100 KB or 200 KB, or fine-tune quality with a slider, and download the compressed image in seconds.
Exact target sizes matter because so many online forms enforce strict upload limits. Government portals, exam registrations, job applications, visa forms and university admissions often reject photos over 20 KB, 50 KB or 100 KB. Instead of guessing with quality settings, choose the size the form demands and let the compressor hit it automatically while keeping the image as sharp as possible.
Compression runs on your own device using efficient web workers, so even large photos from a modern phone camera compress quickly. There are no watermarks, no sign-ups and no daily limits — compress as many images as you like, compare the before and after sizes, and see exactly how much space you saved.

Frequently Asked Questions
How do I compress a photo to 50KB?
Upload your photo, keep the mode on "Target file size", choose the 50 KB preset and click Compress Image. The tool automatically adjusts quality and dimensions until the file fits under 50 KB. This works for JPG, PNG and WebP images and is ideal for exam forms and government portals that enforce a 50 KB photo limit.
How do I compress an image to 20KB for a government form?
Select the 20 KB preset in target-size mode and compress. Very small targets need aggressive compression, so the tool may also scale the image down slightly to fit. If the result looks too soft, try cropping the image to just the required area first — a smaller area compresses to 20 KB with better quality.
Does compressing an image reduce its quality?
Some quality loss is unavoidable when shrinking file size, but the compressor uses smart encoding to keep photos looking good. In quality mode you control the trade-off yourself: 80–90% is usually indistinguishable from the original, while 50–70% gives much smaller files with minor softness that is fine for web use and form uploads.
Are my images uploaded to a server?
No. All compression happens locally in your browser using JavaScript and web workers. Your images never leave your device, which makes this tool safe for passports, ID cards, signatures and other sensitive documents. You can even disconnect from the internet after the page loads and compression still works.
What image formats can I compress?
You can compress JPG/JPEG, PNG and WebP images. JPG generally compresses to the smallest size for photographs. PNG files with large flat-color areas also shrink well, though photos saved as PNG are best converted to JPG first — you can use our PNG to JPG converter, then compress.
Is there a limit on how many images I can compress?
No limits at all. Because processing happens on your own device rather than on a server, you can compress as many images as you want, as often as you want, completely free — no sign-up, no watermarks and no daily quota.
