Convert WebP to JPEG on Mac
WebP is Google's modern image format that offers excellent compression, but not every application, editor, or workflow supports it yet. When you save images from the web or receive WebP files, you often need them as JPG for editing, printing, or uploading to platforms that don't accept WebP. Jollycat converts WebP to JPG instantly on your Mac with full quality control and batch support.

How to Convert WebP to JPEG on Mac
Add your WebP images
Drag .webp files from Finder, your Downloads folder, or anywhere on your Mac into the Jollycat window. Drop multiple files for batch conversion.
Choose JPG and adjust quality
Select JPEG as the output format. Set quality to 90% for a good balance, or higher if you need maximum fidelity. Jollycat shows a preview so you can compare before converting.
Convert
Click Convert and your WebP files become standard JPGs in seconds. Everything runs locally on your Mac — no internet needed, no files uploaded anywhere.
When to Convert WebP to JPEG
Editing downloaded web images
Many websites now serve images in WebP format. When you save these images, apps like older Photoshop versions, Lightroom, or Canva may not open them. Converting to JPG gives you universal compatibility.
Printing photos saved from the web
Most photo printing services accept JPG but not WebP. Convert your WebP images to JPG before uploading to print services to avoid rejection or compatibility errors.
Email and document embedding
WebP images often fail to display in email clients and office documents. JPG is the safest format when embedding images in emails, Word documents, or presentations.
WebP to JPEG Conversion Tips
WebP supports both lossy and lossless compression. If your WebP file was saved as lossless, converting to JPG (which is always lossy) will introduce some compression, but the visual difference is minimal at high quality settings.
WebP also supports transparency and animation (like PNG and GIF). If your WebP has transparency, it will be flattened to a solid background in JPG. For transparent WebP files, consider converting to PNG instead.
Jollycat handles both static and animated WebP files. For animated WebP, you can extract individual frames or convert to GIF or MP4.
Frequently Asked Questions
Why can't I open WebP files on my Mac?
macOS has native WebP support in Safari and Preview since macOS Big Sur, but many third-party apps still don't support it. If your photo editor, design tool, or workflow can't open WebP, converting to JPG with Jollycat solves the problem instantly.
Is WebP better quality than JPG?
At the same file size, WebP generally produces better visual quality than JPG thanks to more advanced compression. However, JPG is compatible with virtually every application and device ever made. Converting WebP to JPG trades some compression efficiency for universal compatibility.
Can I batch convert many WebP files to JPG at once?
Yes. Drop any number of WebP files onto Jollycat and convert them all to JPG simultaneously. Jollycat processes files in parallel on Apple Silicon, so even large batches finish quickly.
