Is WebP good enough for scanned artwork?
For display on a screen, yes — at high quality settings the difference from the TIFF is invisible at normal viewing size, and the file is a fraction of the size. What WebP does not preserve is the archival qualities of the original: 16-bit colour depth, CMYK print colour spaces and embedded colour profiles. Serve the WebP and keep the TIFF.
Will converting TIFF to WebP make the file smaller?
Usually, yes. A 12-megapixel photo is around 36 MB as TIFF and around 2.1 MB as WebP — about 94% smaller. Because WebP is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.
Does converting TIFF to WebP lose quality?
A little, by design. TIFF is lossless and WebP is lossy, so some detail is discarded in exchange for a much smaller file. At quality 80–90 the result is visually indistinguishable from the original for photographs. For screenshots, logos or anything with sharp text, stay with a lossless format instead — lossy compression creates visible halos around hard edges.
Is transparency preserved when converting TIFF to WebP?
Yes. Both TIFF and WebP support an alpha channel, so transparent and semi-transparent pixels carry across unchanged — a logo with a cut-out background stays cut out, and soft drop shadows keep their gradient rather than picking up a white halo. Because WebP can compress lossily, a very hard edge against transparency may pick up slight softness at high compression; keep quality at 85 or above for cut-out graphics.
Why won't my browser display a TIFF?
No major browser supports TIFF — it was designed for print and archival workflows, not the web, and its many optional variants make it awkward to implement. Scanners and professional cameras still produce them, which is why conversion is usually the fastest route. Note that a multi-page TIFF holds several images; only the first page is converted here.
How it works, and more about tiff to webp
How it works
- Add your TIFF file. Drag a TIFF file onto the drop zone, or click to browse. You can select several at once.
- Choose your settings. Adjust the quality slider if you want a smaller file or a sharper result. 80 suits most photographs.
- Download the WebP. Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.
Why people convert TIFF to WebP
Putting scanned or archival material on the web — a gallery of digitised documents, product photography from a studio, artwork that was captured at print quality.
The best size of the three targets, and it keeps transparency where the TIFF had it. Sensible when the images are going onto a page rather than into someone's hands.
Worth knowing: WebP is a delivery format, not an archival one. Keep the TIFF as the master copy — it is the version that holds the full bit depth and colour information you paid for when the scan was made.
TIFF and WebP side by side
| TIFF | WebP | |
|---|---|---|
| Full name | Tagged Image File Format | WebP |
| Compression | Lossy or lossless | Lossy or lossless |
| Transparency | Yes — alpha channel | Yes — alpha channel |
| Animation | No | Yes, in the format |
| Browser support | None — no major browser can display TIFF | All modern browsers — Chrome 32+, Firefox 65+, Safari 14+ (2020), Edge 18+ |
| Typical 12 MP photo | ~36 MB | ~2.1 MB |
| Usually used for | Professional print, document scanning and long-term archives | Web images where page weight matters and modern browsers are the audience |
On a typical 12-megapixel phone photo, the WebP output comes out about 94% smaller than the TIFF original. These are order-of-magnitude figures for one kind of image — your own results will vary a great deal, because flat colour, text and line art behave nothing like photographic detail, and the quality slider moves the figure substantially.
What this tool actually produces
Not estimates. Each row below was produced by running the file through this page in a real browser and measuring the result, at the default quality of 82.
| Test image | TIFF in | WebP out | Change |
|---|---|---|---|
| Smooth gradient 1600 × 1200, broad tonal transitions — where banding and blocking show | 5.5 MB | 198 KB | -96% |
| UI screenshot 1440 × 900, dense text on flat panels — the hardest case for JPEG | 3.7 MB | 47 KB | -99% |
| Line-art diagram 1200 × 800, hard edges and large flat areas | 3.7 MB | 15 KB | -100% |
Every test image got smaller, though by very different margins — flat colour and text behave nothing like photographic detail, so treat the closest row to your own content as the useful one. Measured in Chrome 150.0.7871.46; other browsers encode slightly differently.
What to watch out for
- Not accepted by some older desktop software and print workflows
- Slightly slower to encode than JPEG
- Larger than AVIF at the same quality
About the two formats
TIFF is the archival and print standard: lossless, capable of 16 bits per channel, CMYK colour and multiple pages in a single file. It is also completely unsupported by web browsers, which is the usual reason people need to convert one — a scanner or a printer handed them a TIFF and nothing will open it.
WebP is the pragmatic modern choice for the web: roughly 25–35% smaller than JPEG at comparable quality, with transparency and animation that JPEG lacks, and — since Safari 14 in 2020 — support in every browser that matters. It is the format to reach for when you want smaller pages without worrying about fallbacks.
Other conversions
Everything runs on your device — nothing is uploaded, so there is no size limit, no queue and no copy left on a server afterwards. There is more on how browser-based conversion works if you want the detail. Otherwise, browse every image tool.
