Can I compress JPG and PNG files?

Yes. The compressor accepts JPG, JPEG, PNG, and WebP images and processes them in your browser.

Will compression reduce image quality?

Lossy compression can remove image detail. Adjust the quality setting, compare the preview with the original, and keep your source file.

Can I compress multiple images in one session?

Yes. You can select multiple supported images, adjust their settings, and download the processed results.

When to use this

You're about to upload a hero image to your site and it's 4.7 MB straight from the camera. Your email newsletter platform caps images at 1 MB. Shopify is warning you that your product photos are slowing down your store. These are compression moments — you need the same image, just smaller.

The other common trigger is a platform-specific upload limit. Check the current requirement at the destination, then compare the compressed file with that limit rather than relying on a generic target.

If the source is much larger than its displayed dimensions, resize a copy before the final compression pass. This avoids encoding pixels the destination will not show.

For a step-by-step workflow, see how to compress images and check the result.

Good to know

Aim for an upload limit. Enter the destination's file-size cap in KB before choosing an image. The compressor will try to get under it, but some images cannot meet a small target without further resizing or a different supported format. Check the actual output size and appearance before uploading.

If the limit is stated in MB or MiB, use the image file-size budget guide to convert it into a byte target before exporting.

Quality values are encoder-specific. Start with a high setting, lower it in small steps, and inspect gradients, text, faces, and sharp edges at the intended display size.

Results vary by source. Dimensions, existing compression, detail, transparency, and output format all affect the final size. An already optimized image may change very little.

Compare accepted formats. If the destination supports both WebP and JPG or PNG, export copies and choose the smallest result that preserves the detail you need.

Keep your originals. Lossy JPG and WebP settings discard detail that cannot be restored. PNG output may be lossless, but re-encoding can still change file size and metadata. Compress copies, not sources.

Image processing stays on your device. No account or server upload is required for compression. Your image files stay in your browser tab.

Quick Reference

Image type	Inspect closely	Possible output
Photo	Faces, texture, gradients	Compare JPG and WebP
Screenshot	Small text and hard edges	Compare PNG and WebP
Transparent graphic	Edges and alpha blending	Use a format that preserves transparency
