Example review

The Balanced preset gave me a sensible starting point for newsletter photos. I could compare the file sizes and check the result before adding the image to my draft.

Chloe LaurentNewsletter editor

Image compression

Example review

Setting a smaller maximum width helped me prepare a large room photo for a listing. The proportions stayed the same, and I could see the final size before downloading.

Ethan BrooksProperty listing coordinator

Image compression

Example review

For a JPG with small text, I started with Keep more detail. Having named presets makes the choice easier, and I still inspect the letters in the result before using it.

Hana SuzukiIndependent researcher

Image compression

Example review

I tried Smaller file for a photo I wanted to send to our group. Seeing the saved bytes alongside the preview helped me judge whether the softer details were acceptable.

Omar HaddadEvent volunteer coordinator

Image compression

Example review

I can try a compression preset and compare the result before saving my product photo. That is useful when a clasp or engraving needs to remain visible in a smaller file.

Sofia MendesHandmade jewelry seller

Image compression

Example review

One already-small photo did not benefit from another compression pass. The tool kept the original and explained why, so I could try reducing the width instead.

Frequently asked questions

Are my images uploaded?

Your images are processed in this browser and are not uploaded. Sign-in and export allowance checks do not send your images. Download your results before switching tools, refreshing or closing this page.

Which formats can I use?

Import static JPG, PNG and WebP images. Export PNG for transparency or screenshots, or choose JPG or WebP for photos. Animated images are not supported.

Do I need an account?

You can edit and preview without an account. Sign in for one free export per day shared across combine, split, compress and convert, or subscribe for unlimited local exports. Each single-image download or complete ZIP download counts as one export. Local processing does not use cloud credits.

Will compression always make my file smaller?

Results depend on the image and its original encoding. Choose Smaller file for stronger compression or reduce the dimensions. Keep more detail uses gentler compression, and Balanced is the default for everyday sharing. PNG uses lossless encoding without compression presets. When the same format and dimensions produce no savings, the original file is kept. Compare the actual sizes before downloading; your original file is unchanged.

What happens to transparency and metadata?

PNG and WebP support transparency. JPG replaces transparent areas with the background color you choose. Re-encoded exports apply the displayed orientation and remove original EXIF metadata. When compression keeps the original file because encoding did not make it smaller, its original metadata is retained.

What are the current limits?

Add up to 30 static JPG, PNG or WebP images, with a combined source size of 100 MiB. Each image can be up to 20 MiB and 32 megapixels, with a maximum edge of 16384 pixels. Images are processed one at a time using the same settings. Completed results and ZIP downloads are limited to 256 MiB. Animated images are not supported. Download your results before leaving this page.
