About This Tool
ToolsFaction Image Compressor helps reduce image file sizes for websites, email, documents and everyday sharing. Load a JPG, PNG or WebP image, choose an output format and adjust the compression quality. You can also resize oversized images during compression while preserving their aspect ratio.nnThe before-and-after panel shows the original and compressed previews alongside file size, percentage savings and output dimensions. Image processing is designed to happen directly in your browser, so you can optimize files without a traditional upload-and-process workflow.
How to Use
- Drop a JPG, PNG or WebP image into the tool or choose a file from your device.
- Select JPG, WebP or PNG output and adjust the quality level. For photos, JPG and WebP usually provide the most noticeable compression.
- Optionally enable resizing and set maximum width and height values while preserving the aspect ratio.
- Select Compress Image, review the preview and file-size savings, then download the optimized image.
Example
A 3 MB JPG photo can be converted to WebP at a lower quality setting and optionally resized to a maximum width of 1920 pixels. The tool displays the resulting size and percentage reduction before you download it.
Frequently Asked Questions
Which image formats can I compress?
The tool accepts JPG, PNG and WebP images and can export JPG, PNG or WebP in supported modern browsers.
Can I resize an image while compressing it?
Yes. Enable resizing and enter maximum width and height values. You can preserve the original aspect ratio to avoid distortion.
Why does PNG quality behave differently?
Browser PNG export is lossless and does not use the quality value in the same way as JPG or WebP. If file size is the priority for photographic images, JPG or WebP is often more effective.
What happens to transparent images when exported as JPG?
JPG does not support transparency, so transparent areas are placed on a white background when JPG output is selected.
Can compression ever make a file larger?
Yes. A different output format, high quality setting or already optimized source can produce a file that is similar in size or larger. The tool shows the actual result before download.
Are my images uploaded to a server?
Image compression is designed to run directly in your browser using browser image and canvas capabilities.
Is the Image Compressor free?
Yes. ToolsFaction Image Compressor is free to use and does not require sign-up.
