What is the maximum file size?

3 MB. This is set by the Vercel free tier request body limit. For larger images, use the API with a self-hosted instance — there is no size cap when self-hosted.

Does conversion affect image quality?

Lossless formats (PNG, TIFF) preserve every pixel exactly. Lossy formats (JPEG, WebP, AVIF) reduce file size by discarding perceptually insignificant detail. The quality slider controls this trade-off: 80 is a good default for web images, 90+ for print-quality exports, and 60–70 for thumbnails where small file size matters more than sharpness.

Why convert to WebP or AVIF?

WebP is 25–35% smaller than JPEG/PNG at equivalent quality and is supported by all modern browsers. AVIF is 50% smaller still but takes longer to encode and decode. Both formats support alpha transparency. Converting your images to WebP or AVIF before serving them from a website reduces page load times and bandwidth costs significantly.

Does PNG to WebP conversion lose transparency?

No. WebP supports full alpha channel transparency. Converting a PNG with a transparent background to WebP preserves the transparency. AVIF also supports alpha transparency. JPEG does not — converting a transparent PNG to JPEG replaces the transparent areas with white.

Can I convert SVG to PNG or JPEG?

Yes. SVG is accepted as an input format and can be rasterised (converted from vector to pixels) to any of the supported output formats. The output resolution depends on the SVG's viewBox and the browser's rendering. For high-resolution exports, use the API with a custom width parameter.

What quality setting should I use?

For JPEG: 85 for general use, 70 for thumbnails, 95 for high quality. For WebP: 80 for general use, 60–70 for thumbnails. For AVIF: 70 for general use (AVIF's perceived quality is higher than JPEG at the same numeric value). For lossless PNG and TIFF, quality is ignored.

Is it safe to convert TIFF to WebP in the browser?

Yes. The conversion runs entirely in your browser using the Canvas API — your images are not uploaded to any server. No data leaves your device.

Does converting TIFF to WebP reduce quality?

Converting to WebP uses lossy compression, so some quality reduction is possible. The tool uses high-quality settings by default. For archival use, keep the original TIFF file.

Can I convert multiple files at once?

The web UI supports multiple files at once — drag and drop a batch of TIFF images and download them all as WebP. The REST API also accepts individual files for automated batch workflows.

How do I convert TIFF to WebP without software?

Use this tool — no installation required. Drag your TIFF file onto the converter, select WebP as the output format, and click Convert. The result downloads automatically.

TIFF to WebP Converter

Convert TIFF images to WebP format free, in your browser — no upload, no sign-up.

Why convert TIFF to WebP?

WebP files are typically 50–80% smaller than TIFF, making them faster to transfer and cheaper to store. Converting from TIFF (lossless) to WebP (lossy) is a common way to reduce file size when pixel-perfect quality is not needed.

–Web optimisation — replace TIFF assets on your website with WebP to improve page load speed and Core Web Vitals scores.
–Batch conversion of TIFF files in a CI pipeline using the REST API: POST /api/image-converter.
–Quick one-off conversion without installing software — everything runs in your browser.

About TIFF and WebP

TIFF (source)

TIFF is a lossless format used in professional photography and publishing. Files are large but preserve every detail.

WebP (output)

WebP is a modern format developed by Google. It is 25–35% smaller than JPEG or PNG at equivalent quality and is supported by all modern browsers.

Quality note: TIFF is lossless; WebP is lossy. The conversion is irreversible — once you save as WebP, the original pixel data cannot be recovered. For archival purposes, keep a copy of the original TIFF.

How to convert TIFF to WebP

1.Drag your TIFF file (or files) onto the converter above, or click to browse.
2.Confirm the output format is set to WebP. Adjust quality or size options if needed.
3.Click Convert. The conversion runs in your browser — your images are never uploaded.
4.Download the WebP file. For multiple files, a ZIP is downloaded automatically.
