WebP Converter — Convert Any Format Locally
Convert JPEG, PNG, GIF, and AVIF to WebP on your Mac or Windows machine — no upload, no per-file limits, bulk conversion built in.
Quick answer
TinyPixels converts any supported image format to WebP entirely on your device. Choose lossy or lossless mode, set a quality level, and convert a single file or an entire folder — no upload required.
How to convert images to WebP
Download and open TinyPixels
Free to install on Mac or Windows — no account needed to start.
Drop your images or folder in
JPEG, PNG, GIF, and AVIF sources are all supported.
Choose WebP as the output format
Pick lossy for maximum savings, or lossless for pixel-perfect output.
Convert and collect the output
WebP files appear in your output folder — originals stay untouched.
Why convert to WebP
WebP, developed by Google, delivers meaningfully smaller files than JPEG or PNG at equivalent visual quality — typically 25–50% smaller. It supports transparency like PNG and photographic compression like JPEG, making it a genuine replacement for both in most web and app contexts.
Browser support for WebP now exceeds 97% globally, and every major operating system renders it natively. For anyone optimizing website performance, app bundle size, or storage, converting existing image libraries to WebP is one of the highest-leverage changes available.
Convert from any format
JPEG, PNG, GIF, and AVIF all convert to WebP in the same workflow.
Lossy or lossless
Choose the compression mode and quality level per project.
Bulk conversion
Convert entire folders at once — no per-file limit on Pro.
100% local
No upload, no account, no internet connection required.
Converting from each source format
| From | What to know |
|---|---|
| PNG | Alpha transparency carries over cleanly — use lossless WebP if pixel-perfect accuracy matters, lossy for further savings on complex images. |
| JPEG | Lossy WebP is the natural match — expect meaningfully smaller output at equivalent visual quality since JPEG has no efficiency edge here. |
| GIF | Static GIFs convert straightforwardly; animated GIFs need frame-aware conversion to preserve the animation, not just the first frame. |
| AVIF | Both are modern lossy-capable formats — converting AVIF to WebP is typically for compatibility reasons (older browser support) rather than a size win. |
Frequently asked questions
What is the best WebP converter?
TinyPixels is a native desktop app for Mac and Windows that converts JPEG, PNG, GIF, and AVIF to WebP locally, with no upload required and no file count or size limits on Pro.
Does converting to WebP reduce quality?
WebP supports both lossy and lossless modes. Lossy WebP at 80–90% quality is typically visually indistinguishable from the source while being 25–50% smaller. TinyPixels also supports lossless WebP if you need pixel-perfect output.
Can WebP replace PNG and JPEG entirely?
For most web use cases, yes — WebP supports both photographic compression (like JPEG) and transparency (like PNG) in one format, with better compression than either. Browser support now exceeds 97% globally.
Can I convert a whole folder of images to WebP at once?
Yes. TinyPixels processes entire folders in parallel — drop hundreds or thousands of source images and get back WebP versions of all of them in one pass, fully offline.
Do I need to keep my original files after converting to WebP?
Yes, generally. WebP is a great delivery format, but keeping your original PNG or JPEG masters means you can always re-generate WebP (or any other format) later without quality loss from converting an already-lossy WebP file back and forth. TinyPixels writes converted output to a separate folder by default, so originals are preserved automatically.
Does converting an animated GIF to WebP keep the animation?
WebP supports animation natively, similar to GIF but with better compression. Whether a specific conversion preserves animation depends on the tool correctly detecting and re-encoding multi-frame source files rather than only converting the first frame — worth spot-checking the first converted file in a batch of animated GIFs.
What's the difference between lossy and lossless WebP for icons?
For icons and UI graphics with flat colors and sharp edges, lossless WebP often produces very competitive file sizes without any quality tradeoff, since there's less complex data to lose in the first place. Lossy WebP typically only pulls ahead on photographic or gradient-heavy content, where lossless has less redundancy to exploit.
