How to compress a JPG image

  1. Upload a JPG or JPEG file. Click the upload area or drag a file onto it. The file stays on your device.
  2. Set the quality level. Move the slider between 40% and 100%. Lower values produce smaller files, higher values preserve more detail.
  3. Compress and preview. Click Compress image. The tool shows the original and compressed versions side by side with their sizes.
  4. Download. Click Download to save the compressed JPG to your device. Click Reset to start over.

Key features

Fast, in-browser processing

Compression runs locally using the browser canvas. Nothing is uploaded, so results appear almost instantly.

Adjustable quality

Choose any quality level from 40 to 100 and immediately see the trade-off between file size and visible detail.

Private by design

Your image is read and compressed inside your browser. The file never leaves your device.

Side-by-side preview

Compare the original and compressed images before downloading, along with the size reduction and space saved.

Why compress JPG images

Large JPG photos slow down web pages, take longer to send by email, and consume more storage. Reducing the file size has several practical benefits:

  • Faster websites. Smaller images load more quickly, which improves page speed and user experience.
  • Easier sharing. Compressed images attach more reliably to emails and messaging apps.
  • Lower storage use. Keep photo libraries, backups, and cloud folders smaller without deleting files.
  • No visible quality loss at moderate settings. For most web and social media uses, quality levels between 70% and 85% look essentially identical to the original.

Frequently asked questions

Is this JPG compressor free to use?
Yes. The tool is free and requires no account, login, or payment.
Are my images uploaded to a server?
No. Compression happens entirely inside your browser using the HTML canvas API. Your file is read locally and is not sent to any server.
Which file types are supported?
This tool accepts .jpg and .jpeg files. For PNG or WEBP images, use the Image Format Converter first, or the corresponding compressor for those formats if available.
How much can I reduce the file size?
The amount depends on the image and the quality level you choose. Lower quality settings produce smaller files. The preview and statistics show the exact reduction for your file before you download.
Will compression reduce the image dimensions?
No. The tool re-encodes the image at the same pixel dimensions and only reduces the file size through JPEG quality. To change dimensions, use the Image Resizer.
Does the tool work on mobile devices?
Yes. The page and the upload, compression, and download controls are responsive and work on modern mobile browsers.
