Image Compressor
Use this image compressor to reduce image file size before uploading, emailing or publishing pictures online. Select a JPG, PNG or WebP file, choose a quality level and create a compressed JPEG copy in your browser. The original file stays on your device while you compare the before and after file sizes.
How to use this image compressor
Large image files slow pages down, make emails harder to send and can fail upload limits on forms or content management systems. Compression reduces the amount of data in an image while trying to keep the visual result acceptable. This tool draws the selected image to a browser canvas and exports a new JPEG at the chosen quality level, which is a practical format for photos and many web images.
The right quality setting depends on the image. Photos often tolerate moderate compression well, especially when they are displayed at smaller sizes on a page. Screenshots, text-heavy graphics and images with flat colors may show artifacts sooner. Start with a higher quality setting, compare the size, then lower the quality only as much as needed. Always keep your original file if the image matters.
Compression is only one part of preparing images for the web. If a photo is thousands of pixels wide but appears as a small thumbnail, resizing it before publishing can save even more data. Use descriptive file names and alt text in your website or document so people and search engines understand the image. This compressor focuses on file size reduction and does not upload files to a remote image service.
Image Compressor supports a specific image tools workflow instead of trying to be a general dashboard. That focus helps the page match the task described in the title, heading and URL. Visitors can quickly understand whether the page is live, what it is intended to do, and which related utilities are useful before or after the same task.
Because this tool is implemented on the client side, it avoids unnecessary server-side dependencies and keeps routine inputs in the browser. Review the output before using it in published work, account settings, business documents or production data, especially when the result will be copied into another system.
Frequently asked questions
Are my images uploaded?
No. The compression work happens in your browser using a canvas.
What output format does this tool create?
The compressed download is created as a JPEG file.
Will compression reduce image quality?
Usually yes. Lower quality settings reduce file size but may add visible artifacts.
Should I keep the original image?
Yes. Keep the original file so you can create another version later.
