PNG to WebP Converter — Convert PNG to WebP Free Online

The quality slider runs from 20 to 100 and defaults to 90. For UI icons and screenshots, 80-90 keeps text and edges crisp; for photographic PNGs, dropping to 70-80 usually shrinks the file noticeably further with barely visible loss.

Turning on Lossless mode disables the quality slider and re-encodes with every pixel preserved exactly — the right choice for logos, flat-color graphics and screenshots with sharp text where any compression artifact would be visible. It still typically beats the original PNG's size even though it's larger than the lossy quality-controlled output.

For flat-color icons, logos and screenshots with text, switch Lossless mode on so edges stay perfectly sharp with no banding. For photographic PNGs, leave Lossless off and set the quality slider to 75-85 — you'll get a much smaller file with a difference that's hard to spot at normal viewing sizes.

Yes. WebP supports a full alpha channel just like PNG, so every transparent pixel is preserved exactly regardless of the quality or lossless settings you choose — nothing gets flattened to a solid color.

Yes. Batch mode converts up to 60 PNG files with Premium or 200 with Pro using the same quality or lossless settings, then returns one ZIP. A single clean PNG-to-WebP result can be previewed and downloaded without creating an account.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 files on Premium or 200 on Pro, set your options once, and every file is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 files on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 11 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking image gets refused.

Two things to check. First, what the receiving app actually accepts — plenty of upload forms say "images" and mean JPG only. Second, whether the file really is what its name claims: renaming a HEIC to .jpg does not convert anything, and that single mistake is the most common reason a "converted" file is still rejected. Run the real conversion and the extension will match the contents.

No. You can run PNG to WebP and download the free result without an account, and it carries no watermark. Premium is what you buy when the limits start to bite: up to 60 files in one batch, larger uploads, no daily cap, and the original-resolution result. Nothing is revealed at the download step that was not visible before you started.

No — PNG to WebP runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.
