Compress Image to 500KB
Free tool to compress or reduce any JPG, PNG or WebP image to 500KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 500KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 500KB. Nothing is uploaded; all compression happens on your own device.
A 500 KB allowance is not aimed at passport-sized crops. At 413×531 px a JPEG cannot exceed about 51 KB whatever quality you pick, so it will never fill 500 KB. Targets this size are meant for full-resolution photographs — a postcard photo, or a portrait kept at its original dimensions. Left unresized, a 1240×1593 px portrait lands at about 498 KB against this target, with no loss you could see.
Which forms ask for this size
No Indian or Pakistani exam portal in our reference sets a 500 KB photo limit — UPSC tops out at 300 KB and NEET, JEE and NTS at 200 KB. A 500 KB limit is far more common on job-application portals, university admission systems and general document upload forms.
What to expect at this size
At 500 KB compression is essentially invisible. A full-resolution portrait keeps detail you could not distinguish from the original even zoomed in, and the practical question is usually whether your photo is large enough to justify the size at all. Reaching 500 KB takes roughly 1366×1755 px — around 2.4 megapixels — at good quality.
How to compress an image to 500KB
- 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 500 KB and leave the resize option switched off. Reducing the dimensions is exactly what prevents a photo from using a 500 KB allowance.
- Click Compress. With the original dimensions intact the result uses close to the full allowance — around 498 KB for a 2 MP portrait — and stays visually identical to the source.
- Download. Check the before/after preview, then download your 500 KB image, ready to upload anywhere.
Frequently asked questions
Which forms actually ask for 500KB?
Mostly job portals, university applications and document upload systems rather than exam bodies. Indian and Pakistani exam portals generally cap photographs between 20 KB and 300 KB.
My photo is 3MB and the limit is 500KB. Will it look bad compressed?
No. Going from 3 MB to 500 KB at the same dimensions removes data the eye cannot see. Visible loss on a photograph starts well below 100 KB.
How do I compress an image to 500KB?
Upload your image, set the target to 500 KB, and click Compress. imageto10kb searches for the best quality that stays under 500 KB, then lets you download the result.
Will the quality drop?
For small targets like 500KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 500KB allows.
