Compress Image to 50KB
Free tool to compress or reduce any JPG, PNG or WebP image to 50KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 50KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 50KB. Nothing is uploaded; all compression happens on your own device.
50 KB is a comfortable target for a passport-sized photo. A 2 MP phone portrait cropped to the standard 413×531 px lands at about 44 KB against a 50 KB limit, with the face still sharp — background texture is what gives way first. This is the band most Indian and Pakistani exam portals aim at, so where a form quotes a range rather than a ceiling, working near the top of it costs you nothing.
Which forms ask for this size
SSC photo (20–50 KB), UPSC photo (20–300 KB), UPSC signature (20–100 KB), IBPS and SBI photo (20–50 KB), RRB photo (50–100 KB) and NTS photo (50–200 KB).
What to expect at this size
Here is something worth knowing before you start: at the standard 413×531 px passport size, a JPEG physically cannot get much past 51 KB, even at maximum quality. There simply is not enough pixel data. So a 50 KB target is effectively free — the result lands around 44 KB with no meaningful loss. But if a form demands a minimum of 50 KB, as RRB and NTS do, you cannot get there at 413×531 px. You need larger pixel dimensions, not higher quality.
How to compress an image to 50KB
- Open imageto10kb. Drag your photo onto the box above, or click to choose a JPG, PNG or WebP file from your device.
- Set the target to 50 KB, or tap the preset. If your form also states pixel dimensions — 413×531 px is the usual passport crop — tick “Resize to exact pixel dimensions” and enter them, because portals check both.
- Click Compress. The tool searches the quality range for the best result that still fits under 50 KB. On a standard passport crop that lands around 44 KB.
- Download. Check the before/after preview, then download your 50 KB image, ready to upload anywhere.
Frequently asked questions
My form wants at least 50KB but my file keeps coming out smaller. Why?
Because your pixel dimensions are too small to hold that much data. A 413×531 px photo tops out near 51 KB. Increase the width and height — do not just raise the quality — and the file size will follow.
RRB wants 50–100KB. What dimensions should I use?
RRB specifies 320×240 px for the photo, which is smaller still, so reaching 50 KB needs the full quality range. If you cannot hit the minimum, re-crop from the original photo at full resolution rather than from an already-compressed copy.
How do I compress an image to 50KB?
Upload your image, set the target to 50 KB, and click Compress. imageto10kb searches for the best quality that stays under 50 KB, then lets you download the result.
Will the quality drop?
For small targets like 50KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 50KB allows.
