Free image compressor and WebP converter
Make photos smaller for your website and listings: compress JPG, PNG and WebP, convert to WebP or AVIF, and resize, up to 20 images at a time. It runs in your browser with the open-source codecs from Squoosh, so your images are never uploaded, and location data is removed unless you choose to keep it.
Add images to start. Nothing is uploaded: they stay on this device.

How to use it
- Add your images. Drop up to 20, choose them, or paste one with Ctrl+V. They're compressed straight away.
- Pick a format and quality. WebP for websites, JPEG for marketplaces, AVIF for the smallest files, PNG for logos and screenshots. Add a max width or height to shrink big camera photos.
- Check the result. Each image shows its size before and after. Open "Compare" and drag the divider to see whether you can spot a difference.
- Save. Download each image, or all of them in one ZIP. Changed a setting? Press "Compress again".
Image sizes for Google Shopping, Shopify, Etsy, eBay and Amazon
What each platform's own help page says, checked on 30 October 2026, with our suggested settings. Platforms change their rules, so follow the link before a big upload. None of the pages we could read lists AVIF, so use AVIF for your own website, not for marketplace uploads.
Google Shopping (Merchant Center)
- At least 500 × 500 px for all product images from 31 January 2027; Google recommends about 1500 × 1500 px or more.
- No image over 64 megapixels and no file over 16 MB.
- Accepted: JPEG, WebP, PNG, GIF, BMP and TIFF. No borders, watermarks or overlays.
Our suggestion: WebP, quality 80, max 3000 px.
Shopify
- Images up to 5000 × 5000 px (25 megapixels) and smaller than 20 MB.
- For square product images, 2048 × 2048 px usually displays best.
- Shopify calls PNG the best file type for most product images, then JPEG; WebP, HEIC, GIF, TIFF, BMP and SVG are also accepted.
Our suggestion for photos: JPEG, quality 80, max 2048 px (much smaller than PNG). Keep PNG for logos and graphics.
Etsy
- Etsy recommends at least 2000 px wide and tall, and at least 635 px for the first photo so it isn't shown lower in search.
- Images over 1 MB may not finish uploading on a slow connection.
- Only .jpg, .gif, .png, .svg and .heic files (no WebP), and transparent PNGs aren't supported.
Our suggestion: JPEG, quality 75, max 3000 px, and aim for under 1 MB.
eBay
- Photos must be at least 500 px on the longest side.
- No added borders, text, artwork or watermarks.
- The picture policy doesn't give a recommended size or file limit.
Our suggestion: JPEG, quality 80, max 1600 px, sharp enough to zoom.
Amazon
Amazon's image requirements sit in Seller Central behind a sign-in, so we haven't quoted them here. Check them there before you upload. JPEG is the most widely accepted format, and a quality of 80 to 85 keeps fine product detail for zoom.
Selling products? Clean up the photo first
Free background remover with marketplace presets
Cut the product out, put it on white, and square it up with presets for Google Shopping, Amazon, eBay, Etsy and Shopify, each checked against that marketplace's published guidance. Then bring the result back here to shrink it. Batch Pro (US$19 once, opening soon) will do every photo in one run: its waitlist opens on that page once you've cut out three product photos, because it uses your computer's graphics chip and checks that first.

Questions
Are my images uploaded?
No. The page downloads the encoders from our site (once, when you first use a format) and then does all the work inside your browser. Your images never leave your device and nothing is stored. Formats you've already used keep working if your connection drops.
What does "Keep EXIF" do, and why is it off?
Phone and camera photos carry EXIF details: the camera, its settings, the date and often the GPS location where the photo was taken. With "Keep EXIF" off (the default) all of it is removed, so a photo you post doesn't give away where you live or work. Tick it to keep the camera, date and copyright details in JPEG, WebP and PNG files; the location stays out unless you also tick "Include GPS location". AVIF files never keep EXIF here.
Which format should I choose?
WebP for your own website and Google Shopping: much smaller than JPEG at the same quality. JPEG for marketplaces such as Etsy, which doesn't accept WebP. AVIF makes the smallest files and works in modern browsers, but marketplaces don't list it. PNG is lossless, so use it for logos, screenshots and graphics with sharp edges, not photos.
What quality setting should I use?
Start with 75 for WebP and JPEG and 50 for AVIF (Squoosh's defaults). At those settings most photos look the same as the original at normal size. Use "Compare" to check, and go higher for close-up product detail or text.
Why is a file bigger after compressing?
The original was already well compressed, the quality is set high, or a photo was saved as PNG. The result shows "bigger" in that case: keep your original, or try a lower quality or another format.
Is it free, and are there limits?
Yes, free, with no sign-up and no watermark. Up to 20 images at a time (clear the list for the next 20) and up to 50 megapixels each. It uses your own device's processor, so a big batch on an older phone takes a while.
Built on open source
The encoders come from Squoosh (Google Chrome Labs, Apache-2.0), packaged by jSquash (Apache-2.0): MozJPEG (IJG and BSD licences), libwebp (BSD), libavif and libaom (BSD), OxiPNG (MIT) and the resize crate's Lanczos3 filter (MIT). This software is based in part on the work of the Independent JPEG Group. ZIP files are made with fflate (MIT). Licences and notices: vendor/NOTICE.txt.
