Each tool here does one job. Drop your files in and download the result: HEIC, HIF or AVIF to JPG, a JPEG XL encode, a transparent cutout, a square crop, a PDF. There is no prompt to write, and most pages have nothing to set. Three images a month need no signup, a free account gives you 25, and images and PDFs are processed in memory, never saved to disk. Need something that is not listed? Describe it in Magic Flow.
Instant iPhone photo conversion for universal compatibility.
Convert Fuji, Canon & Sony HIF photos to universally compatible JPEGs.
Convert any HEIF variant to JPG: .heif, .heic and .hif, mixed in one batch.
Turn modern AVIF files into high-quality JPEGs that work with every app and device.
Convert Fuji, Canon & Sony HIF photos to AVIF while preserving 10-bit quality.
Re-encode JPEGs as JPEG XL, one high-quality path. Chrome 155, Firefox 158 and Safari decode JXL; serve it with a fallback.
Decode AVIF and re-encode as JPEG XL, one high-quality path. Standard-range output.
Rasterize SVG assets to WebP with transparency kept: smaller than PNG and supported by every modern browser.
Rasterize SVG files to AVIF with full transparency, usually much smaller than PNG.
Rasterize SVG files to JPEG XL with full transparency and strong compression.
Rasterize SVG files to pixel-exact PNG with transparency kept, for anywhere that will not take an SVG.
Rasterize SVG files to JPG at any size, with transparent areas filled white, for places that only take JPEG.
Re-encode PNG files as JPEG XL: high-quality compressed by default, pixel-exact lossless on request.
Cut out the subject and download a transparent WebP: AI removal, full alpha, smaller than PNG.
Cut out the subject and download a transparent AVIF, with full alpha in a smaller file than PNG.
Crop a batch of images to a perfect square; AI finds the subject in each one and centers the crop on it.
Resize to eBay's 1600px and convert any photo to JPEG.
Combine WebP (and PNG, JPG or AVIF) images into one multi-page PDF, a page per image.
Combine up to 20 JXL images into one PDF, a page per image, stored as standard JPEG so it opens anywhere.
Bundle iPhone and iPad photos into one shareable PDF, a page per photo.
Convert MP4 to smaller, web-friendly WebM, entirely in your browser: nothing uploaded, free.
Convert WebM to H.264 MP4 that plays on iPhone, Mac and Windows, entirely in your browser: nothing uploaded, free.
A tool page is the quickest route when the job matches it: one fixed conversion, nothing to learn. For anything else, Magic Flow takes a plain-English instruction such as "Remove the background, transparent PNG" or "Square crop and optimize for eBay" and does the job in one pass. In Chrome, the Mochify extension adds a right-click "Convert to" menu for any image on a web page. For folders and automation, the Mochify CLI, the hosted and local MCP servers and the REST API run the same encoder; the API documentation has every parameter.
Images and PDFs travel over HTTPS to api.mochify.app, are processed in memory and discarded as soon as the job finishes. Nothing is written to disk, nothing containing your files is logged, and nothing is used to train AI. Metadata, including GPS location, is stripped by default. Video conversion runs in your browser, so the video never leaves your device. The architecture page has the detail.
