Image Format Converter

Convert between PNG, JPEG, WebP, GIF, BMP, SVG, AVIF, HEIC and more. Everything runs locally in your browser — your images are never uploaded to any server.

Notes:

• Batch support: drop multiple images at once, or even an entire folder
• Duplicate filenames in one batch automatically get -1, -2 suffixes
• Output formats: WebP / JPEG / PNG, encoded natively by the browser
• Files already in the target format are skipped to avoid a second lossy round
• HEIC files need an extra decoder library (about 1.4 MB, loaded once the first time a HEIC file appears)
• WebP encoding relies on native browser support (Chrome / Edge / Opera); Safari and Firefox cannot encode WebP yet
• Higher quality slider values mean better image quality and larger files; 70–85 is usually plenty for everyday use
