Lossless baseline for further work.
TIFF preserves every detail of the source JPEG, which prevents additional quality loss during subsequent edits or re-encoding. The original JPEG compression cannot be undone, but no new artifacts will be introduced.
WHY CONVERT
01
TIFF preserves every detail of the source JPEG, which prevents additional quality loss during subsequent edits or re-encoding. The original JPEG compression cannot be undone, but no new artifacts will be introduced.
02
TIFF is accepted by a wider range of image viewers, editors, and content systems than JPEG. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
TIFF is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

| LIMITS | Limited only by your device's memory and CPU. Multi-GB files OK on desktop. | Typical 100 MB to 1 GB per-file caps, plus rate limits. |
A lossy format for photographic images that strikes a strong balance between size and quality.
Typical uses
Photos, web images, email attachments.
A flexible, often lossless format for high-quality print and archival imagery. Supports layers, multiple pages, and many compression schemes.
Typical uses
Scanning, print prepress, archival storage.
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
No. JPEG to TIFF conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Yes — once the page has loaded, JPEG to TIFF conversion works without an internet connection. Re-open the page once to cache it.
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
