What is JPG compression?
JPG compression reduces the file size of a JPG file while keeping it as visually close to the original as possible. Instead of uploading files to a remote server and waiting for processing, Pixvert's JPG compressor runs the entire operation locally in your browser using the Canvas API, so JPG files never leave your device.
JPG uses lossy compression based on how the human eye perceives color and detail, which is why a well-compressed JPG can be 50-70% smaller than the original with virtually no visible difference.
JPG compression reduces file size significantly while preserving visual quality. Smaller JPGs load faster on web pages and take less space in emails and cloud storage. Whether you're preparing files for a website, an email, or cloud storage, compressing JPG images first means faster uploads, less bandwidth used, and quicker load times for anyone who opens them.

Frequently Asked Questions
How much smaller will my JPG be?
Typically 50-70% smaller, depending on the original quality setting and image content. Photos with lots of detail compress less than simple graphics.
Will I see quality loss?
At the default quality level, compression is designed to be visually lossless — you would need to zoom in significantly to spot any difference.
Is it safe to compress my images here?
Yes. Everything happens locally in your browser using the Canvas API — your files are never uploaded to a server.
Is there a file size limit?
There is no hard limit set by Pixvert, but very large files depend on your device’s available memory to process smoothly.
Can I compress multiple files at once?
Yes, drop several files at once and click Compress All — every file is processed and can be downloaded individually or as a ZIP.
Can I use the compressed images commercially?
Yes, Pixvert only reduces file size — it does not alter your rights over the image or add any watermark.
