Image Converter

Change image format in one step

Upload an image, pick the output format, and download the converted file. Runs in your browser — no resizing or compression.

SVG output embeds the rasterized image. SVG uploads are rasterized when exporting PNG, JPEG, or WebP.

Guide: convert image formats in the browser

Design hands off alpha PNGs; builds want WebP or AVIF for LCP. Desktop batch conversion slows pipelines — local conversion speeds prototypes.

Files are read via the File API and converted client-side — images are not uploaded to WebDevTools servers. Best for icons and screenshots without user data.

Use when preparing `<picture>` sources, favicons, or OG thumbnails. Run through the compressor if weight still exceeds performance budgets.

Step by step

  1. Select one or more files — PNG, JPEG, WebP, and other browser-supported formats appear in the list.
  2. Pick output format — WebP/AVIF shrink size; JPEG for photos without alpha; PNG keeps transparency.
  3. Tune quality if available — Lower quality saves bytes — visually check on retina displays.
  4. Download and reference in the project — Update Next/Image imports or CDN assets — remove obsolete files from the repo.
