How to convert JPG to TIFF
- Drop your JPG files on the box above, or click it to choose them (up to 30 at once).
- Press Convert. Each file is processed on your device and shows its old and new size.
- Download the files one by one or take them all as a ZIP.
What changes when you convert JPG to TIFF
- Every decoded pixel is written exactly — TIFF is lossless here. Converting cannot restore detail JPG compression already discarded; it only stops further loss.
- JPG images have no transparency, so there is nothing to lose there.
- Camera details and GPS location (EXIF) are not copied into the new file. Photo orientation is applied to the pixels first, so the result is the right way up.
- Expect a much larger file: TIFF here is uncompressed, about width × height × 4 bytes — roughly 48 MB for a 12-megapixel photo.
About JPG and TIFF files
JPEG is the standard format for photographs. It compresses by discarding fine detail the eye is unlikely to miss, so files are small but every re-save loses a little more.
TIFF is the format of printing, scanning and archiving. The files written here are uncompressed, so they are large, but every pixel is kept exactly. It is a good choice for print shops, scanning workflows and archives that ask for TIFF.
Limits
Up to 30 files of 25 MB each per batch and images up to 50 megapixels — beyond that browsers run out of memory, so the tool says so instead of producing a broken file. Files that are not images, or are damaged, are rejected with the reason.
