Convert TIFF to WebP — Massive Files, Tiny Output
Shrink 500 MB TIFF scans to 5 MB WebP without visible quality loss. 16-bit, CMYK, LZW, multi-page — all handled automatically. Runs entirely in your browser.
In-browser TIFF → WebP conversion
Drop .tif / .tiff files of any size. The engine decodes through ImageMagick 7 (handling 16-bit, CMYK, LZW, JPEG-in-TIFF), normalises to 8-bit RGB, and re-encodes with adaptive quality. Color profiles are preserved.
Supported input formats
- ✓ JPG / JPEG — Photos, portraits, web content
- ✓ PNG — Screenshots, icons, transparent images
- ✓ HEIC / HEIF — iPhone photos, Apple formats
- ✓ TIFF — Scans, prints, high-resolution archives
- ✓ GIF — Animations and static GIFs
- ✓ BMP, PSD & more — Anything ImageMagick can decode
How the conversion works
- 1. DropDrag files or a whole folder into the box below. Folder structure is preserved in the output ZIP.
- 2. AnalyzeEach image is analyzed for entropy and content type. The engine picks per-image quality settings targeting PSNR ≥ 44.5 and SSIM ≥ 0.95.
- 3. EncodeConversion runs on all of your CPU cores in parallel via Web Workers. EXIF, ICC color profiles and geolocation are copied onto the WebP output.
- 4. DownloadWhen the batch is done, a ZIP containing every converted WebP downloads automatically. No re-upload, no waiting on a server.
TIFF is for archives. Stop using it on the web.
TIFF is the right format for masters and prepress. It is the wrong format for everything downstream. WebP closes the gap.
TIFF is for archives, WebP is for everything else
TIFF has ruled professional imaging since 1986 — 16-bit color, CMYK, multi-page documents, lossless LZW or uncompressed storage. It is the right format for archival masters and print workflows. It is absolutely the wrong format for the web, email, cloud galleries or anything mobile. A single TIFF scan from a professional scanner can easily hit 200–500 MB.
How much smaller? Typically 99%
Converting a lossless TIFF photograph to WebP routinely produces files that are 1% the size of the original. A 300 MB flatbed scan becomes a 3 MB WebP that is visually identical to the source at normal viewing distance. For archival images with scanned fine print, SciZone's PSNR/SSIM targeting keeps the text sharp.
16-bit, CMYK and LZW are handled automatically
Most TIFF converters choke on 16-bit per channel, CMYK color spaces, LZW compression, or legacy JPEG-in-TIFF files. SciZone decodes every TIFF variant through ImageMagick 7 — the same library that powers much of the professional imaging world — so the formats your scanner produces just work.
Your ICC color profile follows along
TIFFs from calibrated scanners and prepress workflows carry embedded ICC color profiles (Adobe RGB, ProPhoto, device-specific CMYK profiles). SciZone extracts the profile during decoding and re-embeds it in the WebP output so color rendering stays faithful on calibrated displays.
TIFF vs WebP at a glance
| Criterion | TIFF | WebP |
|---|---|---|
| Typical file size for scans | 100% (huge) | 1–3% |
| Bit depth | 8 / 16 / 32-bit | 8-bit (10-bit via HDR) |
| Color spaces | RGB, CMYK, LAB, YCbCr | sRGB (with ICC profile) |
| Lossless compression | LZW / ZIP / none | Yes |
| Multi-page / multi-frame | Yes | No (first page only) |
| Web browser support | Unsupported | Universal |
| Typical use case | Archival master | Web, email, galleries |
How to convert TIFF to WebP
Four steps. Works with 16-bit, CMYK, LZW and multi-hundred-megabyte scans.
- 1
Drop your TIFF files
Drag single TIFFs, folders of scans, or entire archive exports onto the drop zone below. Extensions .tif, .tiff and .TIFF are all recognised.
- 2
Decoded by ImageMagick
The decoder runs in WebAssembly and handles 8-bit, 16-bit, CMYK, LZW, ZIP and JPEG-in-TIFF variants automatically. 16-bit channels are normalised to 8-bit for WebP output.
- 3
Adaptive quality search
For each image the engine targets PSNR ≥ 44.5 and SSIM ≥ 0.95. High-detail scans with fine text or line art get encoded at higher quality; flat regions get more aggressive compression.
- 4
Download a fraction-of-the-size ZIP
Expect the output ZIP to be 1–5% the size of the input TIFF set. Everything streams through your browser — even a 10 GB batch of scans never uploads anywhere.

TIFF to WebP — Frequently Asked Questions
Will SciZone handle a 500 MB TIFF file?
Yes, assuming your browser has enough RAM. TIFFs up to several gigabytes have been tested in 64-bit browsers. The decoder streams tiles when possible, but very large single-image TIFFs eventually hit the browser's per-tab memory limit — around 4 GB of working memory on most desktops.
Are 16-bit TIFF scans supported?
Yes. 16-bit per channel TIFFs are decoded at full precision and then down-converted to 8-bit for the WebP output (WebP is 8-bit). For archival workflows where you need 16-bit preserved, keep the original TIFF as a master and use WebP only for distribution.
What about CMYK TIFFs from prepress workflows?
They are converted automatically. ImageMagick reads the CMYK data, applies the embedded ICC profile, and converts to sRGB. The resulting WebP is tagged with the sRGB profile so it displays correctly on screens.
Does SciZone support multi-page TIFFs?
It decodes the first page of a multi-page TIFF. Full multi-page-to-animated-WebP conversion is on the roadmap but not yet enabled. For now, split your multi-page TIFF into individual files before dropping.
How much smaller will my TIFF archive become?
For lossless-LZW photographic TIFFs, expect 95–99% reduction. For CMYK prepress TIFFs, expect 90–97%. For scans of text documents, expect 80–90%. SciZone reports the exact per-file savings after each run.
Is the ICC color profile preserved?
Yes. The ICC profile is extracted during TIFF decoding and re-embedded in the WebP output so calibrated displays render identical colors. If your TIFF uses a device-specific CMYK profile, it is first converted to sRGB because WebP is an RGB format.
Can I convert a scanner's output folder in one go?
Yes. Flatbed scanners often produce hundreds of TIFFs in a single session. Drop the whole folder — SciZone parallelises the batch across your CPU cores and writes the output ZIP with the folder structure preserved.
Is this safer than uploading my TIFF archive to an online converter?
Much safer. Archive TIFFs often contain sensitive material — medical scans, legal documents, unreleased artwork. SciZone never uploads the file contents; the conversion is 100% local. You can verify this by opening DevTools → Network and watching during a conversion run.
