Image Compressor.
Drop an image, pick output format and quality. We compress in your browser using canvas. No upload, no signup. Faster pages, smaller files.
Compression happens in your browser. Original file never leaves your machine. Best results: WebP at 80 to 85 for photos, PNG for graphics with text.
Images are the biggest cause of slow pages on small business websites. A single uncompressed hero photo from a phone camera can be 5 to 10 MB. The same image at 200 KB looks identical to the human eye but loads 25 to 50 times faster. The lift to Core Web Vitals, to bounce rate, and to mobile usability is substantial. The only thing standing between most small business sites and a 90 Lighthouse score is image compression discipline.
This tool compresses any image in your browser. You pick the file, choose JPG, PNG, or WebP, and tune the quality. We render the original and the compressed version side by side with the before-and-after file sizes. Nothing leaves your machine. The compressed image downloads as a standard file you can upload to your website, your Google Business profile, your Instagram, or your packaging.
How to use the image compressor
Click Pick an image and select a JPG, PNG, or WebP file from your computer or phone.
Pick the output format. WebP gives the smallest file with the same visual quality. JPG is the safest universal format. PNG is best for graphics with text or transparency.
Slide the quality between 40 and 98. 80 to 85 is the sweet spot for photos. 90 plus for marketing material. 65 to 75 for blog images.
Click Compress. The before and after preview shows side-by-side with both file sizes, so you can confirm there is no visible quality drop.
Click Download to save the compressed file. The original on your computer is unchanged.
Upload the compressed image wherever you need it: website, Google Business, Instagram. Watch your page speed and Lighthouse score climb.
For batch use, compress each image individually. Browser-based compression scales to a few dozen files comfortably.
Why this matters for your business
Three reasons image compression is the single highest-ROI page speed fix.
Images dominate page weight. On a typical small business homepage, images make up 60 to 80 percent of total page bytes. Cutting that in half cuts overall page weight by 30 to 40 percent in one move, with no other engineering work.
WebP beats JPG. WebP gives roughly 30 percent smaller file size at the same perceived quality. Every major browser including Safari has supported it since 2020. There is no real reason to ship a JPG today, except in tools that still do not accept WebP uploads.
Mobile users feel it most. Half of your visitors are on 4G or 5G with limited data plans. A 5 MB hero image both costs them more money and makes your site feel slow. A 200 KB hero image loads instantly even on a poor connection.
Tips for better results
- For photos, use WebP at 80 to 85 quality. The visual difference from the original is almost invisible.
- For graphics with text or sharp edges, use PNG. JPG and WebP introduce subtle artifacts on text.
- Compress at the target display size. A 4000 by 3000 photo for a 800 by 600 display position wastes 90 percent of its bytes.
- Reduce image dimensions before compression. Most photos uploaded to small business sites are 2x to 5x larger than the screen needs.
- After compression, eye-test the result. If you can see degradation, increase the quality slider by 5 to 10.
- For Google Business photos, target 1 MB or less per image. Google compresses them anyway; smaller uploads mean faster posting.
- For Instagram, target 800 KB or less. Anything more is wasted because Instagram re-compresses on upload.
Example
A real-world walkthrough
A clinic owner uploads a hero photo from her phone for the homepage. The original is 4032 by 3024 pixels at 4.7 MB. She loads it into the compressor, picks WebP, sets quality to 82, and clicks Compress. The output is 1024 by 768 pixels at 187 KB. Side-by-side, she cannot tell the difference. She downloads the WebP and uploads it to her Neweb website. The next morning her Lighthouse mobile score moves from 71 to 92, and her PageSpeed Insights LCP improves from 3.4 s to 1.6 s.
Frequently asked questions
Is the compression really happening in my browser?
Yes. The browser uses the standard HTML canvas API to redraw the image and encode it into the chosen format at the chosen quality. The original file never leaves your machine.
Why is WebP smaller than JPG?
WebP uses a more modern compression algorithm (VP8 / VP9 derivative) that achieves better compression at the same visual quality. The trade-off is older browsers that do not support WebP, but every modern browser now does.
Will my image lose quality?
At quality 80 and above for photos, the visual loss is usually invisible. At quality 70 and below, you can start to see artifacts. The before-and-after preview lets you check.
What about transparency?
WebP and PNG both support transparency. JPG does not. If your image has a transparent background, do not choose JPG.
Can I resize images here too?
Currently this tool only compresses. To resize first, use a quick image editor like Photopea (free, browser-based) to reduce dimensions, then bring the result here to compress.
How big a file can I compress?
Browser memory limits start to bite around 50 MP or 100 MB. Most small business images are well under both. For very large source files, resize first.
Will this work on my phone?
Yes. The tool runs in any modern mobile browser. Image quality settings and downloads work the same as on desktop.
Why does my downloaded file have a generic name?
Browser security stops us from reading the original filename. The download is saved as compressed.webp or compressed.jpg by default. Rename after download.
