Convert JPG photos to TIFF for a printer or an archive without uploading them — the file is written in your browser at the original dimensions.
The request almost always comes from someone else: a print shop that only accepts TIFF artwork, a journal with a figure-format policy, a stock agency, a records department digitizing paperwork. JPG is what cameras, phones, and design exports hand you; TIFF is what those workflows are built around. Converting is a two-minute job, and this page does it without a desktop editor or an upload form.
This is worth being blunt about: TIFF is a lossless format, but it cannot undo compression that already happened. A JPG threw away detail at the moment it was saved, and wrapping the decoded result in a TIFF preserves exactly what is left — no new artifacts, but no recovered sharpness either. The output satisfies a TIFF-required rule; it does not turn a heavily compressed photo into a master file. If the camera raw, the original TIFF, or a PNG export still exists somewhere, convert from that instead.
The TIFF is written uncompressed at your image’s original dimensions, so a 3 MB JPG can easily become a 40 MB TIFF — expected, and part of why archives like the format. Browsers cannot display TIFF, so the downloaded file will not preview in a tab; open it in Photos, Preview, or an image editor. Decoding and encoding both happen in a Web Worker on your own device, three files at a time, with before and after sizes shown per file and a ZIP for the whole batch. No account, no watermark, no daily cap.
No. TIFF stores the decoded JPG losslessly, so nothing degrades further, but detail the JPG discarded when it was saved cannot be brought back.
JPG compresses aggressively; the TIFF written here is uncompressed. A tenfold or larger increase is normal, and it is what print and archive workflows expect.
No browser displays TIFF. Use Windows Photos, macOS Preview, or any image editor — the file is valid, browsers simply never added support.
No. Everything runs in your browser, so photos of documents, IDs, or private work stay on your machine.
