Compress images without installing software
This tool shrinks photo and graphic files by re-encoding them in your browser. Use it when an image is too heavy for a website, email, or form upload.
How compression works here
Your file is drawn onto an HTML canvas and exported with the quality you choose. Processing stays on your device — the image is not uploaded to Toolora servers for compression.
Default output is JPEG at the selected quality. That usually reduces camera photos a lot. If the source is a transparent PNG, expect the transparency to be lost when exporting as JPEG.
Tips for better results
- Photos: try 70–85% quality first
- Need a specific pixel size too? Use Image Resizer before or after compressing
- Want WebP for the web? See JPG to WebP or Image Converter
Limitations
- Maximum 20 MB per image
- Animated GIFs are not preserved as animation
- Browser memory can limit extremely large megapixel images
- Quality is a tradeoff — the tool cannot promise a target kilobyte size

Frequently Asked Questions
Does compression keep the original format?
By default the compressor re-encodes to JPEG using your quality setting, which is usually best for photos. Transparent PNGs become opaque when saved as JPEG.
Will lower quality always look bad?
It depends on the photo. Start around 70–80% and only go lower if you still need a smaller file. Screenshots with sharp text often look worse than natural photos at the same setting.
Is my image uploaded to a server?
No. This tool draws your image onto a canvas in the browser and exports a new file locally.
What is the file size limit?
Images up to 20 MB are accepted. Very large pixel dimensions may be slow or limited by browser memory.
