How it works
The TIFF to JPG converter converts TIFF files — the standard format for scanned documents, professional photography, print workflows, and archival images — to web-friendly JPEG. TIFF files are large (typically 10–100MB) and not supported by web browsers as displayable images. JPEG is compact and universally supported.
TIFF (Tagged Image File Format) is the professional and archival standard: it supports lossless compression, 16-bit color depth, CMYK color space, and multiple layers. Scanners, professional cameras, and print workflows output TIFF. But web pages, email, and most web apps don't accept TIFF — JPEG conversion is required.
How to use it: upload a TIFF file. Set the JPEG quality (85 is a good balance of quality and file size for most use cases). The tool handles multi-page TIFF (extracts the first page for conversion) and both RGB and CMYK color spaces. Download the resulting JPEG.
File size comparison: a typical 8×10" document scan at 300 DPI is approximately 25MB as uncompressed TIFF. The same image as JPEG at quality 85 is approximately 1.5–3MB — 8–17x smaller.
16-bit to 8-bit: TIFF files may contain 16-bit color channels (65,536 tonal values per channel) vs. JPEG's 8-bit (256 values per channel). The conversion applies a tone-mapping step to preserve visual fidelity in the 8-bit output.
Color space: CMYK TIFF files (from print workflows) are converted to sRGB for JPEG output. The conversion uses standard ICC profiles.
Privacy: TIFF decoding and JPEG encoding run in a WebAssembly module in your browser. No file is uploaded.
Frequently Asked Questions
- Quality 85 is the standard recommendation. It produces a file visually indistinguishable from the original at typical web viewing sizes while achieving 8–15× file size reduction compared to the uncompressed TIFF. Use quality 90–95 if the images will be viewed at large sizes or zoomed.
- By default, the first page is converted to JPG. Toggle Multi-page mode to convert each page as a separate JPG file, numbered sequentially. Download all pages as a ZIP archive.
- CMYK to RGB conversion uses standard ICC profiles and may shift some colors slightly, particularly vivid reds, blues, and spot colors. For color-critical print-to-screen conversion, use Adobe Photoshop or a color-managed workflow to apply the correct ICC profile transform.
- Processing runs in the browser and is limited by available device memory. TIFF files up to approximately 500MB can be handled on most modern devices. A 500MB TIFF is approximately a 10,000×10,000px 3-channel 16-bit image — common in high-resolution scanning workflows.
