Compress Image to 5KB
Free tool to compress or reduce any JPG, PNG or WebP image to 5KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 5KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 5KB. Nothing is uploaded; all compression happens on your own device.
At 5 KB you are in signature territory rather than photo territory. A scanned signature at the 140×60 px most portals ask for compresses to roughly 3.5 KB, so it clears 5 KB without effort. A full passport photo is the harder case: at 413×531 px it cannot reach 5 KB on quality alone, so imageto10kb reduces the pixel dimensions too, and you should expect visible softening. If your form permits smaller dimensions, set them — that costs far less quality than forcing the quality slider to the floor.
Which forms ask for this size
5 KB sits inside PAN card photo (max 20 KB), PAN card signature (max 10 KB), NEET signature (4–30 KB) and FPSC photo (under 30 KB). In practice a 5 KB requirement almost always means a signature.
What to expect at this size
5 KB is very small, and what it can hold depends entirely on dimensions. A scanned signature at the usual 140×60 px compresses to around 3.5 KB without effort, so it clears 5 KB comfortably. A photograph is a different matter: to fit 5 KB a portrait has to come down to roughly 145×186 px, which is smaller than most forms accept. If a form asks for a 5 KB photo, check the pixel dimensions it also specifies — they are usually small too.
How to compress an image to 5KB
- 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 5 KB. Compressing a signature? Leave the dimensions alone — it will already fit. For a photo, tick “Resize to exact pixel dimensions” and enter what your form asks for, because at 5 KB the dimensions do more work than the quality does.
- Click Compress. imageto10kb searches the quality range first and only shrinks the image if no quality setting gets under 5 KB — so detail is given up in the order that costs you least.
- Download. Check the before/after preview, then download your 5 KB image, ready to upload anywhere.
Frequently asked questions
Can a passport photo be 5KB?
Only at very small pixel dimensions — around 145×186 px. At the standard 413×531 px passport size, 5 KB leaves visible blocking across the face. Reduce the dimensions rather than forcing quality to the floor.
My signature is under 5KB already. Is that a problem?
No. Forms set 5 KB as a maximum, and a smaller file is accepted. Only re-compress if the form also states a minimum size.
How do I compress an image to 5KB?
Upload your image, set the target to 5 KB, and click Compress. imageto10kb searches for the best quality that stays under 5 KB, then lets you download the result.
Will the quality drop?
For small targets like 5KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 5KB allows.
