Edit Image

Resize Image

Resize an image to a target width and/or height (aspect ratio kept if one is blank).

Image

Choose a file to convert. It's processed locally — never uploaded. Tip: add several files to convert them all at once.

{ } How to use

  1. Choose the image.
  2. Enter a width, a height, or both. Leave one blank and it is calculated to keep the aspect ratio.
  3. Select Process, then download the PNG.

{ } How it works

Resize Image works on the file you upload. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Inputs

  • Image — upload a file (image/png,image/jpeg,image/webp,.png,.jpg,.jpeg,.webp); it is read locally in your browser
  • Width (px, blank = auto) — a value (default: "1280")
  • Height (px, blank = auto) — a value

Output

A downloadable PNG file — use the Download button in the Output panel.

{ } Common uses

  • Bring a camera photo down to a size a page or a form will accept.
  • Make an image fit an exact box in a layout.
  • Reduce the pixel dimensions of an oversized screenshot.

{ } Limitations

  • The output is always PNG, whatever went in. PNG is lossless, so a resized photograph very often comes out larger in bytes than the JPG it started as, even with fewer pixels. Run Compress Image afterwards when file size is the point.
  • Filling in both width and height will stretch the picture if the numbers do not match its shape. Leave one blank to keep the proportions.
  • Enlarging is allowed and adds no detail: the extra pixels are interpolated, so the result looks soft.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

Yes — add several files and they’re all processed and downloaded together as a ZIP.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

I resized to make the file smaller and it got bigger. Why?

Because the result is a PNG, and PNG stores every pixel exactly — much less efficient for photographs than JPEG. Fewer pixels but lossless storage can still add up to more bytes. Resize first and then compress, and you get both.
