{ } How to use

  1. Choose several images.
  2. Pick the output format, optionally a maximum width, and a quality.
  3. Select Process, then download the ZIP.

{ } How it works

Batch Image Convert works on the files 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

  • Images — add the files to process (image/png,image/jpeg,image/webp,.png,.jpg,.jpeg,.webp); they are read locally in your browser
  • Convert to — choose one — WebP, JPG, PNG (default: WebP)
  • Max width (px, blank = keep) — a value
  • Quality (1–100) — a value (default: "90")

Output

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

{ } Common uses

  • Convert a folder of photographs to WebP for a website in one pass.
  • Shrink a set of screenshots to a consistent maximum width.
  • Standardise mixed formats into one before handing them on.

{ } Limitations

  • The original filenames are not kept. Files come back as image-001, image-002 and so on, in the order they were uploaded, so rename them afterwards or convert one at a time when the names carry meaning.
  • Max width only shrinks. An image already narrower than the limit is left at its own width and never enlarged.
  • Everything is held in memory and zipped in the browser, so a very large batch can exhaust the tab. Work in smaller groups if it fails.

{ } 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.

Can I keep the folder structure?

No. The ZIP is flat and the names are generated. This is built for converting a pile of images quickly rather than for mirroring a directory tree.
