Convert images to verified JPG, PNG, WebP, AVIF, GIF, ICO or BMP files locally.
Add one image or a batch of JPG, PNG, WebP, AVIF, GIF, BMP or HEIC sources and confirm their decoded dimensions.
Choose JPG, PNG, WebP, AVIF, static GIF, multi-size ICO or BMP, then set the format-specific quality, transparency fill or icon fit.
Convert locally, inspect the real encoded result and download one file or a ZIP archive for the batch.
About this tool
Convert images to verified JPG, PNG, WebP, AVIF, GIF, ICO or BMP files locally.
Conversion decodes visible pixels and re-encodes them with a verified destination codec. AVIF uses a local WebAssembly encoder, GIF uses palette and LZW encoding, ICO contains six PNG-backed sizes, and BMP is written as a 24-bit bitmap instead of receiving a renamed PNG payload.
Add one image or a batch of JPG, PNG, WebP, AVIF, GIF, BMP or HEIC sources and confirm their decoded dimensions. Choose JPG, PNG, WebP, AVIF, static GIF, multi-size ICO or BMP, then set the format-specific quality, transparency fill or icon fit. Convert locally, inspect the real encoded result and download one file or a ZIP archive for the batch.
Use JPG for photographs and compatibility, PNG for lossless transparency, WebP or AVIF for compact web delivery, GIF for a broadly supported still palette image, ICO for application icons, and BMP only when an uncompressed bitmap is required.
You can start with JPG, PNG, WebP, AVIF, GIF, BMP, HEIC and export JPG, PNG, WebP, AVIF, GIF, ICO, BMP, ZIP. Actual decoding support can vary slightly by browser.
Image Converter runs in your browser. Your image is not uploaded to Image Toolkit.
