WebP Converter
Convert JPG/PNG to WebP for smaller files — or WebP back to PNG/JPG when compatibility wins.
WebP is the web's workhorse image format: files typically come out 25–35% smaller than JPEG at the same visual quality, with support for transparency like PNG. Converting your site's images to WebP is one of the easiest page-speed wins there is. This converter goes both directions — JPG or PNG into WebP, and WebP back into PNG or JPG for the software that still doesn't accept it (older photo editors, some CMS uploads, email tools).
Drop an image in and the conversion happens instantly in your browser with a live preview and before/after file sizes; a quality slider controls the size/fidelity trade-off for WebP and JPG output. Nothing is uploaded, so there are no size limits or privacy worries. The tool detects direction automatically: drop a WebP file and it defaults to PNG output. Batch-shrinking photos rather than switching formats? The image compressor may be the faster path.
How to use the WebP Converter
- Drop your image (JPG, PNG or WebP) onto the tool.
- Pick the output format — dropping a WebP automatically suggests PNG output.
- Adjust the quality slider for WebP/JPG output and compare the before/after sizes.
- Click Download.
Frequently asked questions
Why use WebP instead of JPG or PNG?
Smaller files at the same quality — typically 25–35% less than JPEG for photos, and often dramatically less than PNG for graphics with transparency. Smaller images mean faster pages, better Core Web Vitals and less bandwidth.
Do all browsers support WebP?
Every modern browser has supported WebP since roughly 2020 — Chrome, Firefox, Safari (14+), Edge and all mobile browsers. Compatibility concerns today are mostly about desktop software and older CMS pipelines, not browsers.
When should I convert WebP back to PNG or JPG?
When a tool refuses the file: older versions of Photoshop, some email marketing platforms, government/enterprise upload forms, and printing services. PNG keeps transparency and exact pixels; JPG is smaller for photos.
Does converting lose quality?
WebP and JPG are lossy, so each save at less than 100% discards a little data — invisible at the default settings. Converting to PNG is lossless: what's in the source is exactly what you get, at a larger file size.
Is my image uploaded anywhere?
No — the conversion uses your browser's built-in encoders and runs entirely on your device. No upload, no queue, no watermark, no file-size limit.
