Up to 20 files at a time, with a 20 MiB input limit per file. Standard limits are 16 megapixels per image, 8192 pixels per side, and 64 MiB of total results. Known low-memory devices use 8 megapixels and 16 MiB of results.

Compressed file size and decoded image size differ. A small file can expand to more pixels than your browser can safely handle. Try a smaller image or export a large TIFF one page at a time.

Changing a format cannot recover missing detail. JPEG output introduces lossy compression. PNG output preserves decoded pixels without adding another lossy encoding step, but cannot reverse earlier JPEG losses.

Yes. After two or more results are ready, use Download ZIP. Individual download links are also available. Keep the page open until you have downloaded what you need.

AVIF depends on native browser decoding. TIFF variants and very large scans may be unsupported. SVG files must be self-contained; scripts, external resources, and some advanced drawing features are rejected. Each tool lists its own limits.

Results are kept only in the current page’s memory until you choose new files or leave. Downloaded copies are usually in your device’s Downloads folder, depending on your browser settings. We cannot recover results after you leave.
