Convert & compress images, PDFs, audio, video and data. 88 tools, all in your browser. Your files never leave your device. Foundry is a complete file-conversion toolkit that runs entirely on your own device. Add a file, get your result, and nothing is ever uploaded. It works fully offline and is private by design. What you can do: Images: convert between formats, resize, compress, crop, rotate, watermark, upscale, remove backgrounds, and read text with OCR. PDF: merge, split, reorder, rotate, compress, redact, sign, add page numbers, and extract text. Audio and video: convert, trim, adjust, turn a video into a GIF, remove a background colour, and more. Change a file's type: switch an image, audio clip, video, or document to a different format. Data and developer tools: work with JSON and CSV, spreadsheets, checksums, QR codes, and more. Private and offline by design: Your files never leave your device. There are no uploads and no servers. No analytics, no tracking, and no ads. Everything keeps working with no internet connection. Free and Pro: Core conversions are free and unlimited. Pro unlocks premium tools such as background removal, OCR, PDF compression and redaction, video transcoding, and unlimited batches. Secure checkout is handled by ExtensionPay, and your files are never involved.
