How Format Convert Works

Format Convert changes images between PNG, JPG, WebP, GIF, BMP and SVG. Convert a screenshot PNG to JPG for email, turn a JPG logo into a transparent PNG, or downsize a BMP from a scanner — all locally, with live size estimates.

Typical Use Cases

PNG to JPEG for email

Convert a transparent PNG to JPEG when the recipient’s system struggles with PNG size.

JPEG to PNG for editing

Turn a JPG into a PNG to edit or overlay without recompression artifacts.

BMP from old scanners

Convert bulky BMP scans to JPEG or PNG to make them usable on the web.

Use JPEG for photos and email attachments, PNG for graphics that need transparency, WebP for the web, and GIF for simple animations. SVG export suits logos and icons that will be scaled. The live estimates make format decisions easy.

FAQ

Can I convert SVG files?

Yes — SVG is supported as an input format. Raster formats are also exportable, which rasterizes vector content when needed.

Which format keeps the highest quality?

PNG and WebP are lossless and preserve detail best; JPEG trades some detail for much smaller files, which is fine for photos.

Is Format Convert free?

Completely free. All tools on this site are free to use — no sign-up and no usage limits. Ads shown on the site help cover server and development costs.

Are my files safe?

Yes. Files are processed entirely in your browser and never uploaded to any server. Data is cleared when you close the page.

Will conversion reduce image quality?

Conversion uses high-quality encoding — differences are nearly invisible. Formats like WebP can even shrink file size while keeping quality.
