- Click Convert & download and check the savings column. Grab everything with Download all (.zip).
Sizing images for the web properly
Format is only half the win. The full pipeline for fast pages: resize to the largest size the image is actually displayed at (usually 1200–1920px), then convert to WebP here. A 4 MB phone photo typically lands around 150–250 KB after both steps — an order of magnitude faster to load, visually identical in context. Serve a JPG fallback only if you must support pre-2020 clients; for modern sites, plain <img src="photo.webp"> is enough.
FAQ
How much smaller is WebP than JPG really?
For photographs, expect 25–35% smaller at equivalent visual quality. The exact saving depends on the image — this tool shows the before → after size and percentage per file, so you see the real number rather than a marketing claim. Occasionally an already-heavily-compressed JPG won't shrink; keep the original in that case.
Which browsers and platforms support WebP?
Every modern browser — Chrome, Firefox, Safari (since 14), Edge — plus iOS and Android. The stragglers are old software: pre-2020 image editors, some email clients, and office suites. For web publishing, WebP is safe; for email attachments, stick with JPG.
What quality setting should I use for WebP?
0.82 (the default) is the sweet spot for photos — comparable to JPG at 0.9 but noticeably smaller. Go up to 0.9 for portfolio imagery, down to 0.7 for thumbnails.
Does the conversion strip metadata?
Yes — EXIF (camera, date, GPS) doesn't survive the re-encode. For web publishing that's normally desirable. To strip metadata while keeping the file a JPG, use Remove EXIF.
Is anything uploaded to a server?
No — conversion runs in your browser. Drop a folder of full-resolution photos without worrying about upload time or privacy.
