You can also open a tool directly. The table lists every supported direction; each destination checks the file contents and its own size, color and animation limits before conversion.

Separate images and data tables into batches by source format. Mixed selections are not added automatically. JPEG and JFIF share the same image format; HEIC and supported HEIF photos share a destination. Identification is a routing hint, not a promise that a file is convertible.

For SVG artwork, PNG keeps sharp lossless pixels, JPG adds a solid background for compatibility, and WebP can keep transparency with lossy encoding. Check whether the receiving app accepts WebP. ICO combines selected 16–256 px layers for favicons or applications that require icon files. For photos that need to become one document, choose JPG or HEIC to PDF; these produce image pages without searchable text or OCR.

CSV to JSON preserves values as strings, with optional headers. JSON to CSV accepts flat object arrays, keeps number text and all columns, and enables visible formula protection by default. CSV/TSV and JSON extensions are routing hints; the destination validates encoding and contents. Compare the data tools and their limits.

The selection stays in memory for one minute while you choose. Opening a destination transfers it once in the same tab, where you review settings and start conversion yourself. Refreshing or closing the tab clears your files. Clear selection cancels the handoff; there is no saved file history.

The destination applies its own limits: SVG accepts 50 files, 10 MB each and 50 MB total. Photo tools accept 20 MB per file and 100 MB total, while PDF documents accept up to 20 photos. Data tools accept up to 10 UTF-8 files, 5 MB each and 20 MB total. Output dimensions, supported profiles and memory limits are explained on each page. Use smaller batches on phones.
