Tips
- WebP typically offers 25-35% smaller files than JPEG at the same quality
- AVIF is even smaller but takes longer to encode and has less browser support
- Resize images to their actual display size for the biggest savings
- All processing happens in your browser - your images never leave your device
How to Compress Images Without Losing Quality
- Drop your images above. You can add one file or a whole batch; JPEG, PNG, WebP, and AVIF are all supported as input.
- Pick an output format. WebP is the best default for the web: it is 25-35% smaller than JPEG at the same visual quality and supported by every modern browser. Choose AVIF for maximum savings, JPEG for universal compatibility, or PNG when you need lossless graphics.
- Set quality between 75 and 85. This range is visually indistinguishable from the original for photos while cutting file size dramatically. Go lower for thumbnails, higher for hero images.
- Resize to the display size. Serving a 4000px camera photo in a 800px-wide layout wastes bandwidth. Resizing is usually a bigger saving than compression itself.
- Download individually or as a ZIP. Compare the before/after sizes in the results panel before you commit.
Smaller images directly improve Core Web Vitals, especially Largest Contentful Paint (LCP), which Google uses as a ranking signal. For most sites, image weight is the single largest performance budget item, so optimizing images is the highest-impact speed fix available.
Frequently Asked Questions
Are my images uploaded to a server?
No. Compression, resizing, cropping, and watermarking all run inside your browser using the Canvas API. Your images never leave your device, which makes this tool safe for confidential documents, client work, and unreleased product photos. There are no file size limits imposed by a server either; the only limit is your device's memory.
WebP or AVIF: which should I choose?
WebP is the practical default: excellent compression, instant encoding, and universal browser support since 2020. AVIF compresses 20-30% smaller still and shines for large photographic images, but it encodes more slowly. If you need to support very old browsers or email clients, stick with JPEG.
How much smaller will my images get?
Typical results: a 3 MB phone photo converts to a 150-400 KB WebP at quality 80 with no visible difference. PNG screenshots with flat colors often shrink 60-80% as WebP. Combining a resize with format conversion regularly cuts total weight by 90% or more.
Does image compression affect SEO?
Yes, positively. Page speed is a confirmed Google ranking factor, and images are usually the heaviest assets on a page. Faster LCP improves both rankings and conversion rates. Just keep quality at 75+ so visual quality stays high, and use descriptive file names and alt text for image search.
Can I process multiple images at once?
Yes. Drop as many files as you like and they are processed as a batch with the same settings, then downloaded together as a single ZIP. This is handy for product catalogs, gallery pages, and blog migrations.
Is EXIF data (location, camera info) removed?
Yes. Because the image is re-encoded through the browser canvas, metadata such as GPS coordinates, camera model, and timestamps is stripped from the output file. That is a privacy bonus when publishing photos online.
