Frequently asked questions
At the default quality of 80, the difference is invisible to most viewers — WebP is simply more efficient than JPG at the same perceptual quality. If you enable lossless mode, there is zero quality loss. The only scenario where you would notice degradation is at very low quality settings (below 50), which would look bad in any format.
On average, 25–35% smaller than the equivalent JPG. Results vary by content: photos with gradients and smooth tones compress best (30–40% savings), while images with sharp edges or text see smaller gains (10–20%). ConvertYard shows you the exact byte savings per file in your results so you can see the difference immediately.
WebP is supported in all modern browsers: Chrome, Edge, Firefox, and Safari (since version 14, released September 2020). That covers over 97% of global web traffic. If you need to support Safari 13 or Internet Explorer, stick with JPG. For any modern web project, WebP is the right default.
Lossy WebP (the default) discards some pixel data to shrink file size — at quality 80 this is imperceptible. Lossless WebP preserves every pixel exactly, like a PNG, but uses smarter compression than PNG and is typically 25% smaller than an equivalent PNG. Lossless files are 10–30% larger than lossy equivalents. Use lossless for logos, screenshots, UI assets, or images you plan to edit again.
Yes. Drop them all in at once and ConvertYard processes them one at a time in your browser — no uploads, no queues, no server. Speed depends on your device, image dimensions, and the compression effort setting. On a modern laptop, 1,000 average-sized photos typically finishes in 5–15 minutes. Download them all as a single ZIP when done.
Never. Conversion runs entirely in your browser using WebAssembly — the same technology behind browser-based tools like Figma. Your files never leave your device. ConvertYard's servers only deliver the tool's code; they never see your images, filenames, or metadata.
