Convert JPG to WebP online

JPEG has been the web's photo format for 30 years. WebP does the same job with 25–35% smaller files and better handling of fine detail at low bitrates. Convert your JPGs right here: nothing is uploaded and the result is ready in under a second.

Why convert JPG to WebP?

25–35% smaller photos at the same perceived quality, according to Google's own studies.

Fewer artifacts. WebP's prediction-based coding handles gradients, skies and skin tones with less blockiness than JPEG at equal size.

Resize in the same step. Camera and phone photos are 4000+ px wide; set a max width of 1600–2000 px and shrink the file another 4–6×.

Better PageSpeed score. Lighthouse flags JPEGs under 'Serve images in next-gen formats'; WebP clears that audit.

How to convert JPG to WebP

Step 1

Select your JPG files

Click the drop zone or drag and drop your JPG images. Files stay on your device; nothing is uploaded.

Step 2

Choose quality and size

Move the quality slider (80% is ideal for most images) and set a maximum width to downscale oversized images.

Step 3

Convert to WebP

Press "Convert to WebP". Your browser encodes each JPG to WebP in a fraction of a second.

Step 4

Download

Download each WebP file, or grab the whole batch as a ZIP with Pro.

JPG vs WebP for photographs

Both formats are lossy and both target photos. The difference is the compression engine: JPEG (1992) uses 8×8 block DCT with no prediction, while WebP (2010) borrows intra-frame prediction from the VP8 video codec, entropy-codes more efficiently and applies an in-loop deblocking filter. The practical outcome is that a WebP at quality 80 looks like a JPEG at quality 85–90 but weighs a quarter to a third less.

What quality should I pick for JPG to WebP?

For blog images, product photos and portfolio shots, 75–82% is the sweet spot. For full-screen hero images that are partially covered by text, 60–70% is usually acceptable and saves another 30%. Only go above 90% for print previews or photography portfolios where pixel-peeping is expected.

Avoid double compression

Every lossy step discards information. If you still have the RAW or the original camera JPEG, convert that, not a copy that was already re-saved by a CMS or messaging app. Converting a heavily compressed JPEG to WebP still saves space but cannot restore lost detail.

Camera photos
A 12-megapixel phone photo is about 4000×3000 px and 3–5 MB. Displayed in a 1200 px content column, only 9% of those pixels are used. Set max width to 1600 px and quality to 78%: expect 150–250 KB.

JPG to WebP: questions

Yes. JPG and JPEG are the same format; the three-letter extension comes from old Windows file name limits. This converter accepts both .jpg and .jpeg files.

Any lossy conversion discards some data, but at 80% quality the difference is invisible at normal viewing sizes. WebP actually preserves gradients and fine detail better than JPEG at the same file size.

No. Browser-based conversion strips EXIF metadata (camera model, GPS location, timestamps). This is usually desirable for privacy and saves a few extra kilobytes. Keep your originals if you need the metadata.

Yes, with Pro: drop up to 100 JPGs at once and download them as a ZIP. Pro is $4.99/month, $29/year or $59 once.
