Bulk Image Converter — Convert Hundreds of Images Free

There's no fixed limit. Batches of several hundred are common and run in parallel across your CPU cores, so even large batches finish in seconds. It's completely free with no signup.

BatchSet uses multi-core Web Workers to convert images directly in your browser — there's no upload, so there's no waiting on a server.

No. Everything happens locally on your device, which keeps it fast and fully private.

Yes — one click downloads all converted images as a single ZIP file.

Yes, use the Excel Batch Convert tool to convert hundreds of image URLs from an Excel or CSV file.

Input: JPG, PNG, WebP, GIF, BMP, SVG, HEIC and TIFF. Output: WebP, JPG or PNG, free. HEIC photos convert free on the HEIC to JPG page, and TIFF on the TIFF to JPG page.

Up to 10 MB per file with no signup, 25 MB on a free account, 100 MB on Pro and 500 MB on Enterprise. There's no fixed cap on how many files a batch can contain — it's bound by your device, not a server.

Make sure it's a supported image (JPG, PNG, WebP, GIF, BMP, SVG) and isn't corrupted or above your file-size limit. For very large batches, converting in smaller groups avoids hitting your browser's memory limit.

WebP for a website or online store: it is usually the smallest at the same look. JPG when the files go somewhere older, such as email, print shops, upload portals or desktop software. PNG when you need transparency or want to keep every pixel for further editing.

PNG and WebP keep them. JPG has no transparency, so transparent areas come out white. If you need the cut-out kept, convert to PNG or WebP instead.

Yes. The converted JPG, PNG and WebP files do not carry the camera, date or GPS data of the originals. The rotation is applied to the pixels first, so photos taken sideways still come out upright.

Open the folder, select every image with Ctrl+A on Windows or Command-A on a Mac, and drag them onto this page together. Pick one output format and download the ZIP.
