About this resizer tool

Resizing correctly is more than stretching into a smaller canvas. Downscaling by more than 1.6x in one step aliases badly, so this resizer halves the image repeatedly — close to proper box-filtering — then applies a light unsharp mask to restore the apparent sharpness the interpolation removed.

How it works

  1. 1Drop your images in. Drag and drop, paste from the clipboard, or browse. Whole folders are fine — the converter picks up every image it recognises.
  2. 2Tune the output. Pick a format, set the quality or a target file size, adjust dimensions, and dial in the colour. The preview updates as you type.
  3. 3Download. Save a single file, or grab the whole batch as one ZIP. A ten-second sponsored break comes first — that is what keeps the tool free.

Tip: check the preview before downloading

The preview runs the exact same pipeline as the download, including quality and the size target. If it looks right in the preview, the file on disk will look identical — there is no server-side re-encoding step that could change the result.

Format support

Every format that matters, in both directions

The output list only shows formats your browser can genuinely encode, so nothing ever fails silently.

HEIC, TIFF, SVG and ICO are listed because your browser may be able to read them. If it cannot, the file is flagged with an explanation rather than failing silently — and the HEIC page has the fastest workarounds for every device.

The things people actually ask about this conversion.

Almost always — pixels scale with area, and file size scales with pixels. Halving each dimension typically removes 75% of the bytes.
