# Resize Image to KB

Resize an image to fit a pixel box and a KB limit at once, for a form that asks for both. Free, no signup, and the photo is never uploaded.

Canonical page: https://filetity.com/resize-image-to-kb

## Capabilities

- Free: Yes, with no watermark and no page limit.
- Account required: No. There is no account system.
- Processed on device: Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- Formats: JPG, PNG and WebP in. A JPG out, because that is what upload forms ask for and it is the format that can be pushed to a small size.
- Limits: The picture is fitted inside your box with its proportions kept, so one side can come out smaller than the number you typed. It is never stretched to fill the box, because a squashed face or a distorted signature is a worse outcome than a photo that is 200 by 218, and the real dimensions are printed before you save. If your form demands exact proportions, crop it first. A very detailed photo at very small dimensions may not reach a very small limit, and it says so instead of pretending.
- Mobile: Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Offline: Yes. Nothing is downloaded to make this work, so it keeps working with no network connection once the page has loaded.

## Questions

### What numbers should I type?

The ones on the form you are filling. Requirements differ between forms, between departments and between years, and they are stated on the page or in the notice you are uploading to. This tool deliberately does not guess them for you: hardcoding a specification that changes would be confidently wrong for somebody, and typing the two numbers from the form in front of you works for a form nobody has heard of.

### Why is my image smaller than the size I asked for?

Because it is fitted inside the box rather than stretched to fill it. A photo that is 4 by 3 cannot become 200 by 230 without distorting or cropping, so it comes out 200 by 150 or 172 by 230, whichever fits. The result is printed before you save. Most forms state a maximum and accept anything inside it; if yours needs exact dimensions, crop to that shape first and then use this.

### How is this different from the image compressor?

The compressor is asked for a file under a size and the dimensions are not part of the request, so if quality alone cannot get there it scales the picture down, which is the right last resort. Here the dimensions ARE the request. This page holds them and spends quality only, and tells you when it cannot reach the limit, because passing the size check while failing the pixel check is not a result worth having.

### Why does it always give me a JPG?

Because upload forms ask for one, and because it is the format that can be squeezed to a small target. A PNG of a photograph will not reach 20 KB at any useful size; the same picture as a JPG will. A signature scanned as a PNG converts here without trouble.
