Your images never leave this tab.
Open your browser's developer tools, switch to the Network tab, and convert a file. You will see the encoder and its WebAssembly module load from this domain the first time, and then nothing — no upload, no image data, no request carrying your file anywhere. Turn off your Wi-Fi after the page loads and it still works.
TIFF is a print and archival format, not a web one, and no major browser will display it. That is less an oversight than a consequence of the format’s scope: TIFF permits so many combinations of compression, bit depth and colour space that supporting it properly is a significant undertaking.
This converter decodes it in the page and re-encodes to WebP, which every browser displays.
Two things to watch. Multi-page TIFFs — common for scanned documents — convert their first page only. And 16-bit-per-channel scans are reduced to 8 bits, which is invisible for viewing but matters if you are still editing; keep the TIFF as your master in that case.
Frequently asked questions
- Why won't my TIFF open in a browser?
- No major browser supports TIFF. It comes from print and scanning workflows rather than the web, and its enormous range of variants — different compressions, bit depths, colour spaces, multiple pages per file — made it impractical for browsers to support. We decode it in the page instead.
- My TIFF has multiple pages. What happens?
- Only the first page is converted. Multi-page TIFFs are common for scanned documents, where each page of the original becomes a page in the file. If you need every page, a dedicated document tool is the better choice.
- Will a 16-bit TIFF lose precision?
- Yes. WebP is an 8-bit-per-channel format, so a 16-bit scan is reduced to 8 bits per channel. For viewing and web use this is invisible. If you are still editing the image — particularly heavy curve or exposure adjustments — keep the TIFF as your master and treat the WebP as an export.
- How much smaller will the file be?
- Usually dramatically. TIFFs are often uncompressed or use light LZW compression, and scans are frequently at 300-600 DPI. Reductions above 95% are common, and you can resize during conversion if the pixel dimensions are larger than you need.
Other conversions
Each converter opens with the right output format already selected, so the file you drop comes back in the format you came for.
Convert WebP to another format
Convert images to WebP
- Convert PNG to WebP Keep the transparency, drop most of the file size. Lossless mode is one click away if you need pixel-exact output.
- Convert JPG to WebP Typically 25-50% smaller than the same photo as a JPEG, at a quality most people cannot tell apart.
- Convert JPEG to WebP The same conversion as JPG — the two extensions are one format. Smaller files, same picture.
- Convert HEIC to WebP iPhone photos, converted in the browser. No app, no upload, and it works on iOS Safari where most converters do not.
- Convert AVIF to WebP Usually a compatibility move rather than a size one. WebP opens in more places than AVIF still does.
- Convert GIF to WebP Static GIFs convert cleanly and shrink hard. Animated GIFs convert to their first frame — and we will tell you when that happens.
- Convert BMP to WebP BMP stores pixels essentially uncompressed. Expect the file to get very substantially smaller.
- Convert SVG to WebP Turning vector into pixels. You choose the size, because a vector does not really have one.
Convert to PNG or JPG
- Convert HEIC to JPG Turn the photos your iPhone actually shot into the format everything else can open. The pictures never leave your device.
- Convert HEIC to PNG Convert iPhone photos into PNG when the software you are feeding demands it. Lossless, private, and free.
- Convert SVG to PNG Rasterize vector artwork into PNG at the exact size you need, with the transparent background intact.
- Convert SVG to JPG Rasterize vector artwork into JPG for the places that will not take anything else. Free, unlimited, nothing uploaded.
- Convert TIFF to JPG Turn enormous archival scans into files you can actually email. Free, unlimited, and nothing leaves your machine.
- Convert TIFF to PNG Convert archival scans into PNG without losing a pixel — the right choice when the page is text, plans or line art.
- Convert AVIF to JPG You downloaded an AVIF and nothing on your computer will open it. This turns it into a JPG that everything opens.
- Convert AVIF to PNG Convert AVIF into PNG for the software that has never heard of AVIF. Transparency intact, nothing uploaded.
- Convert GIF to PNG Convert GIF into PNG without losing a pixel — and escape the 256-colour palette for good.
- Convert GIF to JPG Convert GIF into JPG for the systems that insist on it. Free, unlimited, and nothing leaves your machine.
- Convert BMP to PNG Shrink uncompressed Windows bitmaps dramatically without losing a single pixel. Free, unlimited, nothing uploaded.
- Convert BMP to JPG Turn enormous uncompressed bitmaps into files you can actually send. Free, unlimited, and nothing leaves your machine.
