Make an image smaller for sharing or upload

Compress JPG, PNG, or WebP images when a photo is too large to send or attach. Compare the output size and appearance before downloading. If the form requires specific pixel dimensions, resize the image first.

Frequently Asked Questions

Add a JPG and select Compress Images. Compare the original and result before downloading. If you need a smaller file, open Adjust settings and try a smaller maximum dimension or lower quality. An already optimized JPG may shrink only a little.
Add the photo and select Compress Images. The default settings limit large images to 2400 px and use balanced quality. Compare the result with the original, then download it. If an upload has a strict file-size limit, adjust the settings and compress again; an exact size is not guaranteed.
PNG uses lossless encoding when you keep PNG, so the quality control does not reduce its colors. Try a smaller maximum dimension or explicitly convert it to WebP. WebP can keep transparency, but it changes the file format.
Yes. Add up to 20 JPG, PNG, or WebP files, then download each result or all results in one ZIP. Each input can be up to 50 MB.
Yes. Choose Use in Image to PDF after compression. The generated images are passed to the PDF converter in this browser tab so you can arrange them into one PDF. WebP is re-encoded for PDF embedding, so the PDF may be larger than the WebP file.
No. Image processing runs in your browser. The site may contact its API for account and daily-use details, but the image contents are not uploaded for compression.

Reduce JPG, PNG, and WebP Image File Size

Use this free online image compressor to reduce JPG, PNG, or WebP file size before sharing, uploading, or turning photos into a PDF. Add one image or a batch and select Compress Images. Compare the before and after sizes and preview the result before downloading. You can adjust quality, maximum dimensions, or output format if the first result needs a different balance. Image processing stays in your browser.

JPG and WebP can be re-encoded at a lower quality. PNG stays lossless when you keep its format, so resizing or choosing WebP may produce a more useful reduction. The tool keeps the original file when a same-size, same-format re-encode would make it larger.

Choose the Reduction That Fits Your Image

Compress JPG Photos

Lower the quality or maximum dimensions of a large photo, then compare the actual file sizes and appearance.

Handle PNG Transparently

Keep PNG for lossless output, or explicitly choose WebP to try a smaller file while retaining transparency.

Download a Batch

Download a specific image or collect all finished images in one ZIP archive.

Continue to Image to PDF

Carry the compressed results into Image to PDF without reselecting the files in this tab.

When a Smaller Image Helps

  • Prepare document photos before creating a PDF
  • Reduce a JPG before attaching it to an email
  • Resize a large PNG graphic for sharing
  • Make a set of WebP images smaller for a website

Will the Image Always Get Smaller?

No. The result depends on the source image and chosen settings. A file that was already optimized may not shrink. Resizing changes pixel dimensions, while lower JPG or WebP quality can soften fine details. Review text, edges, and transparency before using the result.

What Happens to Image Metadata?

The browser redraws and exports a new image during processing, which may discard EXIF, camera, location, color-profile, and other metadata. If those details matter, keep your original image.
