Compress Image to 20KB
Free tool to compress or reduce any JPG, PNG or WebP image to 20KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 20KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 20KB. Nothing is uploaded; all compression happens on your own device.
20 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 19 KB against a 20 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), SSC signature (10–20 KB), PAN card photo (max 20 KB), UPSC photo (20–300 KB), UPSC signature (20–100 KB) and IBPS and SBI photo (20–50 KB).
What to expect at this size
20 KB is the single most commonly demanded limit across Indian exam portals, and it is a comfortable one. A standard 413×531 px passport photo lands around 19 KB with only mild softening — at the size the photo is actually displayed on a form, most people cannot tell. Fine background detail degrades first; the face holds up well.
How to compress an image to 20KB
- 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 20 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 20 KB. On a standard passport crop that lands around 19 KB.
- Download. Check the before/after preview, then download your 20 KB image, ready to upload anywhere.
Frequently asked questions
Why do so many forms ask for 20KB?
It is a practical compromise. 20 KB is small enough that a portal can store millions of uploads cheaply, and large enough that a passport-sized photo still looks acceptable when printed on an admit card.
Will 20KB be too blurry for my admit card?
No. At 413×531 px a 20 KB JPEG prints acceptably at passport size. Blurring becomes a real problem only if the original was already low resolution or heavily cropped.
How do I compress an image to 20KB?
Upload your image, set the target to 20 KB, and click Compress. imageto10kb searches for the best quality that stays under 20 KB, then lets you download the result.
Will the quality drop?
For small targets like 20KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 20KB allows.
