How to convert your images
- Choose your files. Add supported images. You can select up to 20 files per batch, within the displayed size limits.
- Set the result. Choose an output format. Adjust dimensions and, for JPG, WebP or AVIF, quality. Check the transparency background where available.
- Convert and download. Download each result or the batch ZIP. Compare file size and appearance before replacing any original.

Convert a whole batch in your browser
Drop in up to 20 images, choose JPG, PNG, WebP, AVIF, GIF, BMP, TIFF or ICO, and convert them together. ConvitAll reads JPG, PNG, WebP, HEIC, AVIF, TIFF, GIF, BMP, ICO and static SVG files, so iPhone photos, web downloads and scans all work in the same place. Download each result or one ZIP.
Why nothing needs to be uploaded
Your browser can decode and encode images itself, and for formats it cannot handle, such as HEIC or TIFF, ConvitAll loads a decoder that runs inside the page. The work uses your own device, so your photos are not sent to a server, stored or queued. That also means no account, no daily limit and no watermark.
Control size and quality
Set a quality from 10 to 100, pick a longest side such as 1,920 pixels, or enter a maximum size in KB for JPG, WebP or AVIF. Automatic size keeps very large images within 32 megapixels. The same private approach powers ConvitAll's PDF and audio tools.
Questions and answers
Is ConvitAll really free?
Yes. Converting, compressing and resizing images costs nothing, needs no account and adds no watermark. You can run as many batches as you like, up to 20 files at a time.
How can a website convert images without uploading them?
Modern browsers include image decoders and a canvas for drawing pixels, and they can run WebAssembly codecs. ConvitAll uses these on your device, so the conversion happens in your browser tab rather than on a remote server.
Can I convert iPhone HEIC photos here?
Yes. ConvitAll includes a HEIC decoder that runs in your browser, so you can convert iPhone photos to JPG or PNG on Windows, Mac, Android or Chromebook without installing an extension. Live Photo video and camera metadata are not carried over.
Does converting keep my photo’s location data?
No. EXIF fields such as GPS position, camera model and capture time are not copied into converted images. That makes it easy to share a photo privately, but keep the original if you need that information later.
