Resize Image in KB – Exact Size, Right in Your Browser
Set a maximum KB, an optional minimum, and the pixel size. The photo never leaves this device.

Preset figures last checked 10 November 2026. A portal may count KB as 1,000 or 1,024 bytes, so the file is kept inside both.
Your files never leave this device. There is no account and no watermark on the download.
Set the target size: KB range + pixels / cm / DPI
Type a maximum KB and, if the form also has a floor, a minimum. Add width and height in pixels, or pick a verified exam preset. If a notice gives centimetres but no DPI, you choose 200 or 300 and the page says that choice is not from the notice.

Quick presets: 10–20KB, 20KB, 20–50KB, 50KB, 100KB, 200KB
The chips fill the KB fields. 10–20 and 20–50 are ranges, so the file is kept inside both ends. A single number such as 20 KB is a ceiling: the file stays under 20 KB whether a portal counts 1,000 or 1,024 bytes.
Reduce image size in KB (without changing dimensions)
Tick “Keep the current pixel dimensions” when the form cares about the file size and not a new crop. Quality drops first. If the photo still cannot fit, the page says so instead of quietly shrinking it.
Increase image size in KB (without changing pixels)
Making a file larger is a different job. Use Increase photo size in KB when a form rejects a file for being under a minimum. That page can pad the JPEG or upscale it, and it says which one it did.
On mobile, laptop or iPhone: no app needed
On a phone, tap the box and use the camera roll or the Files app. On a laptop, drop the photo. iPhone HEIC is decoded here when the browser can; if it cannot, you get a plain message, not a broken download.
Why your form keeps rejecting the image (byte limits, JPG only, min KB)
Portals reject files that are over the maximum, under the minimum, or not really JPEG. This page exports JPEG and shows the size in bytes, in KB counted as 1,000, and in KB counted as 1,024. Stay inside the range rather than on the exact edge.
Privacy: your photo never leaves your device

FAQ
How do I resize an image in KB and pixels at the same time?
Set the maximum KB and type the width and height in pixels, or pick a verified preset that already has both. The photo is fitted inside that frame without stretching, then the JPEG quality is adjusted until the file is inside the KB window.
How do I resize an image in KB without losing quality?
Start with a modest reduction. A smaller KB always discards some detail. If you also keep the pixel size, the only lever left is JPEG quality, and the page will refuse a target it cannot hit without a useless file.
How can I increase image size in KB without changing pixels?
Open Increase photo size in KB and choose “Keep the same pixels and pad the file.” The picture does not get sharper. The file only gets large enough for a minimum-KB rule.
How do I reduce image size in KB on mobile / iPhone?
Open this page in Chrome or Safari, tap the box, and pick the photo. No app install. If the photo is HEIC and this browser cannot decode it, export a JPEG from Photos and try again.
Can I reduce image size in KB without changing dimensions?
Yes. Tick “Keep the current pixel dimensions.” Only the compression changes. Untick it if you also need fewer pixels to reach a very small KB.
How do I resize an image in KB in Paint (and is there an easier way)?
Paint can resize pixels, not a target KB. Here you set the KB directly and download a JPEG. Nothing is uploaded.
How do I resize an image in KB and cm for an exam form?
Pick a verified preset, or type centimetres via the preset page. If the notice has no DPI, choose 200 or 300 yourself — that number is labelled as not from the notice. SSC live photos are not a file you can prepare here.
