Compress Image to 300KB
Free tool to compress or reduce any JPG, PNG or WebP image to 300KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 300KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 300KB. Nothing is uploaded; all compression happens on your own device.
A 300 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 300 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 275 KB against this target, with no loss you could see.
Which forms ask for this size
UPSC Civil Services photo, where 300 KB is the stated ceiling of a 20–300 KB range, and the Pakistan passport and NADRA photo, which varies but sits roughly between 60 and 350 KB.
What to expect at this size
300 KB is the most generous limit any major exam portal sets, and at ordinary upload dimensions it is effectively lossless. A full-resolution portrait compressed to 300 KB is indistinguishable from the original even when you zoom in. The practical risk here is the opposite of the usual one: a passport-sized crop tops out near 51 KB and will land nowhere near 300 KB, which only matters if the form sets a minimum as well as a maximum.
How to compress an image to 300KB
- 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 300 KB and leave the resize option switched off. Reducing the dimensions is exactly what prevents a photo from using a 300 KB allowance.
- Click Compress. With the original dimensions intact the result uses close to the full allowance — around 275 KB for a 2 MP portrait — and stays visually identical to the source.
- Download. Check the before/after preview, then download your 300 KB image, ready to upload anywhere.
Frequently asked questions
UPSC allows 20–300KB. Which end should I aim for?
Either is accepted, so aim high. A photo near 300 KB carries more detail onto your admit card than one squeezed to 20 KB, and UPSC rejects only files outside the range.
My UPSC photo is only 50KB. Will it be rejected?
No. 50 KB sits inside the 20–300 KB range, so it passes. It is likely a passport-sized crop, which physically cannot reach much beyond 51 KB — that is normal, not a fault.
How do I compress an image to 300KB?
Upload your image, set the target to 300 KB, and click Compress. imageto10kb searches for the best quality that stays under 300 KB, then lets you download the result.
Will the quality drop?
For small targets like 300KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 300KB allows.
