Is this TIFF to WEBP converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple TIFF files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

Does WebP support the full colour depth of a 16-bit TIFF?

WebP outputs 8-bit colour. If your TIFF has 16-bit depth, the conversion tone-maps it to 8-bit, which is sufficient for all web display purposes.

Will transparency in my TIFF be preserved in WebP?

Yes — if your TIFF has an alpha channel, WebP will preserve the transparency in the output file.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert TIFF to WEBP?

TIFF is the professional format of choice for print, scanning, and archival work — but its file sizes are impractical for web delivery, email, or sharing via messaging apps. A print-ready TIFF at 300 DPI can easily be 50–100 MB. WebP bridges professional quality and web practicality, achieving excellent results at file sizes 10–30× smaller than TIFF.

WebP is supported by all modern browsers and is accepted by most web platforms including WordPress (as of version 5.8), Shopify, Squarespace, and Wix. For photographers and designers who work in TIFF for their master files but need web-ready versions, converting to WebP gives them a format that's fast to load, maintains excellent quality, and is accepted everywhere modern images are displayed. Google PageSpeed Insights specifically recommends WebP as a next-generation image format.

Lossless WebP preserves the exact pixel data from the TIFF — the resulting file is lossless but substantially smaller than the TIFF, making it a good archive format for images that don't need to stay in TIFF. Lossy WebP at high quality settings (85–95%) is typically visually indistinguishable from the TIFF source while being 5–20× smaller. If the source TIFF has 16-bit color depth, note that WebP is an 8-bit format — the high bit depth information will be converted to 8-bit, which is fine for display but means you're no longer working with the full dynamic range of the master file.

Quality & file size: TIFF to WEBP

Typical file sizes: TIFF 20–70 MB → WEBP 1–3 MB.

Both TIFF and WEBP use lossy compression. We transcode at high quality settings (equivalent to WEBP's recommended web quality) to minimize generational loss.

Color depth: TIFF supports 32-bit, WEBP supports 8-bit.

Transparency: TIFF supports transparency. WEBP preserves transparency.

Your TIFFfiles are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
