JPG to TIFF Converter

Convert JPG to TIFF entirely in your browser, with no upload: your JPEG file is read into memory locally and rewritten as a TIFF on your own device, so nothing is sent to a server. Most people reach this page not because they want a "better photo" (converting cannot make one), but because a downstream workflow demands TIFF: a print lab or photographer's proofing chain that requires a lossless master, a document or archival system (scanned legal, medical, student, or government records) where TIFF is the retention standard, or an OCR/GIS pipeline that expects TIFF input. This tool handles both jpg and jpeg sources and writes a real, lossless TIFF.

What this conversion actually does (and does NOT do)

Converting JPEG to TIFF does not recover or improve image quality. JPEG already discarded pixel data permanently through lossy DCT compression, and that loss is irreversible. Wrapping those same pixels in a TIFF cannot reconstruct what was thrown away. What it does do is stop FURTHER generation loss: once the image lives in a lossless TIFF, future edits and re-saves will not keep degrading it the way repeatedly re-saving a JPEG would.

Expect a large file-size increase, not a decrease. A roughly 2MB JPEG commonly becomes a 15-20MB TIFF, because TIFF stores the full pixel data uncompressed or with lossless compression rather than JPEG's aggressive lossy scheme. TIFF supports lossless compression (LZW, ZIP/Deflate) or none at all. For 8-bit images, LZW can cut size by around 60%, while ZIP/Deflate is consistently more effective. A counterintuitive detail: for 16-bit images, LZW can actually make the file about 5% larger than uncompressed and slower to write, so ZIP is the better choice there. Your JPEG source is only 8-bit per channel, so the output stays 8-bit; converting to a 16-bit-capable container does not add bit depth the original never had. Neither JPEG nor baseline photographic TIFF carries a true alpha channel, so no transparency is gained or lost in this specific conversion (it only matters if you wrongly expect PNG-like behavior).

When to choose JPG to TIFF vs the alternative

Choose TIFF when a specific destination requires it: a print shop asking for a lossless master, an OCR engine, or an archive with multi-year retention. JPEG's lossy compression suits continuous-tone photos but handles sharp-edged black-and-white scanned text poorly, which is exactly why document workflows move scans into TIFF. If your real goal is a smaller file for the web or email, do not convert to TIFF at all; keep the JPEG or run it through image compression instead. If you need transparency or web delivery, a PNG or WebP target via the general image converter is the right route, since TIFF gives you neither.

How to convert

1. Drop one or many JPG/JPEG files into the box. They are read locally in your browser, never uploaded.
2. The output format is pre-selected to TIFF. TIFF is lossless, so there is no quality slider to set for this target.
3. Convert. A single file downloads directly; multiple files download as a ZIP, with no count cap.

No upload. It runs on your device.

The conversion logic is Rust compiled to WebAssembly and executes inside your browser tab. There are zero network requests for your file: the JPEG is read into memory, rewritten as TIFF, and handed back as a download, all locally. This matters most here because TIFF is the format people reach for with confidential scanned documents, patient records, student files, legal exhibits, and government archives, none of which should ever touch a third-party server. After the page loads once, it works offline (airplane mode included). There is nothing to delete afterward because nothing was ever uploaded, and you can verify it yourself in your browser's DevTools Network tab: no request carries your image.

No limits

Unlimited batch conversion, no file-count or size cap, no watermark on output, no sign-up, and no ads. Server-based converters cap free tiers and queue your files behind an upload; this does neither.

Frequently asked questions

Does converting JPG to TIFF improve image quality?

No. The JPEG already discarded pixel data permanently through lossy DCT compression, and converting to TIFF cannot rebuild it. What you gain is the prevention of further generation loss on future edits and re-saves, since TIFF is lossless.

Why is my TIFF file so much bigger than the JPG?

TIFF stores the full pixel data uncompressed or with lossless compression, while JPEG uses aggressive lossy compression. That is why a roughly 2MB JPEG commonly expands to a 15-20MB TIFF. The pixels are the same; only the storage efficiency differs.

Is JPG to TIFF lossless?

The TIFF write step is lossless: it preserves every pixel coming out of the JPEG without discarding more. However, those pixels already carry the loss baked in when the file was first saved as JPEG, so "lossless" means no new loss from this point forward, not a pristine original.

Can I convert multiple JPGs into one multipage TIFF?

TIFF is multipage-capable, which is why it dominates document scanning and fax workflows where many pages live in a single file. Combining several JPEGs into one multipage TIFF is a common archival use, especially for scanned multi-page records.

Which TIFF compression should I use, LZW or ZIP?

For 8-bit images (which is what a JPEG source produces), LZW can cut size by about 60%, but ZIP/Deflate is consistently more effective. For 16-bit images LZW can paradoxically make the file around 5% larger than uncompressed and slower, so ZIP is the safer general choice.

Is TIFF better than JPG for printing and archiving?

For those purposes, yes. TIFF is the de facto archival and master-record standard, used by libraries and institutions for 10+ year retention, and print labs prefer a lossless TIFF master. JPEG remains better for web delivery and email where small size matters more.

Will my photos be uploaded to a server when I convert?

No. The entire conversion runs in your browser via Rust compiled to WebAssembly, with zero network requests for the file. You can confirm this in your browser's DevTools Network tab, where no request carries your image.

Can I convert JPG to TIFF offline or without an internet connection?

Yes. Once the page has loaded once, the WebAssembly module stays in your browser and the converter works fully offline, including airplane mode. No connection is needed to process a file because no file is ever sent anywhere.

Is there a file-size or batch limit?

No. There is no file-count or file-size cap, and batch conversion is unlimited. Single files download directly and multiple files download together as a ZIP.

Why do print shops and OCR software ask for TIFF instead of JPG?

OCR engines including ABBYY FineReader and Tesseract treat TIFF as a preferred input, and JPEG's lossy compression handles sharp black-and-white scanned text poorly. Print and archival workflows want a lossless master rather than a re-compressed lossy file, which TIFF provides.
