Compress Image to 15KB
Free tool to compress or reduce any JPG, PNG or WebP image to 15KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 15KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 15KB. Nothing is uploaded; all compression happens on your own device.
At 15 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 15 KB without effort. A full passport photo is the harder case: at 413×531 px it cannot reach 15 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
15 KB falls inside SSC signature (10–20 KB), PAN card photo (max 20 KB), IBPS and SBI signature (10–20 KB), NEET signature (4–30 KB), NEET postcard photo (10–200 KB) and JEE Main photo (10–200 KB).
What to expect at this size
For a signature, 15 KB is generous — a 140×60 px scan lands near 3.5 KB, well under. For a photograph it is tight but workable: a portrait needs to come down to about 301×387 px to produce a 15 KB file at good quality, or accept visible softening if it must stay at 413×531 px. This is the size band where reducing dimensions genuinely beats reducing quality.
How to compress an image to 15KB
- 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 15 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 15 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 15 KB — so detail is given up in the order that costs you least.
- Download. Check the before/after preview, then download your 15 KB image, ready to upload anywhere.
Frequently asked questions
Should I reduce quality or dimensions to hit 15KB?
Dimensions, if your form allows it. A 301×387 px photo at 15 KB looks considerably better than a 413×531 px photo squeezed to the same 15 KB, because the smaller image is not being asked to encode as much.
SSC wants a signature between 10 and 20KB but mine is 4KB. What now?
That is below the minimum, so scan again at higher resolution or a larger area. A signature that is already tiny cannot be padded up to 10 KB by re-encoding it.
How do I compress an image to 15KB?
Upload your image, set the target to 15 KB, and click Compress. imageto10kb searches for the best quality that stays under 15 KB, then lets you download the result.
Will the quality drop?
For small targets like 15KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 15KB allows.
