Everything happens in your browser: no image is sent to a server.
Nothing leaves your browser
The photo is opened and rewritten by your own browser, using the same engine that displays images on web pages. No file is sent to a server, nothing is stored and, once the page has loaded, the tool keeps working even without internet.
Compress a photo in three steps
- 01
Select the photos
Drag up to 20 images or tap Choose images to pick them from your gallery. Each file can be up to 25 MB.
- 02
Adjust the quality
The default of 85 already cuts most of the weight with no visible loss. For camera photos, enable the 1920 px cap on the longest side.
- 03
Compare and download
The list shows the size before and after with the reduction percentage. Download one by one or all in a .zip.
When to compress an image
Camera and phone photos
A 12-megapixel photo weighs 4 to 6 MB. At quality 85 with the longest side capped at 1920 px it drops under 500 KB and still looks great on screen.
Websites and online stores
Light images load faster and help your search ranking. Compress the catalog photos in bulk before uploading.
WhatsApp and social media without losing the original
Send the compressed version and keep the original file at print quality.

Questions about compressing images
Which image formats does the tool accept?
JPG, PNG, WEBP, GIF (first frame only), BMP and AVIF, as long as your browser can open the format. JPG, PNG and WEBP keep their format on output; GIF, BMP and AVIF are saved as JPG.
Does it compress HEIC, the iPhone photo format?
No. Browsers cannot open HEIC/HEIF, so the tool warns you and skips the file. On iPhone, go to Settings, Camera, Formats and choose Most Compatible to shoot in JPG, or share the photo as JPG before compressing.
How many images can I compress at once?
Up to 20 images per batch, at most 25 MB each. They are processed one after another with a progress bar, and you download each result or all of them in a .zip.
Is transparency preserved?
For PNG and WEBP, yes: the format is kept and the transparency channel comes along. GIF and BMP are saved as JPG, which has no transparency: transparent areas get a white background. To keep a GIF's transparent background, convert it to PNG with the image converter.
Which quality should I use?
80 to 90 is the sweet spot: the difference from 100 is invisible to the eye and the file gets much smaller. Below 70, blocks start showing up in flat areas. PNG does not use quality because it is a lossless format: to shrink a PNG, cap the resolution or convert it to JPG or WEBP. If compression gains nothing, the tool keeps the original file.
Are my photos uploaded to a server?
No. The whole compression runs in your browser: the files never leave your computer or phone, are not stored in any database and are seen by no one. Close the tab and it is gone.
Does it work offline?
Yes. Once the page has loaded, the tool does not depend on a connection: you can switch off Wi-Fi and keep compressing.
What is the difference between compressing and resizing?
Compressing keeps the width and height and reduces the weight by adjusting the encoding quality. Resizing changes the number of pixels: a 4000 px photo becomes 1920 px, for example, which usually cuts more weight than any quality setting. Here you can do both at once with the option to cap the longest side.
