Limits on your device depend on its memory. Larger files may still work; the tool warns you first.
How it works
- 01 Choose or drop one or more JPG, PNG or WebP images.
- 02 Pick “By quality” and a level, or “To a file size” and a target such as 200 KB.
- 03 Optionally open More options to convert to WebP or to use the slower, smallest encoder.
- 04 Press Compress and download each image, or all of them as one ZIP.
About this tool
Choose a target and review the size estimate. Some files cannot reach the target at a usable quality; check the downloaded result. Hushdesk makes them lighter in two ways: set a quality level and let the size follow, or set a target size such as 200 KB and let the tool try different settings to approach your target. JPEG and WebP are re-encoded with care, PNG is optimized without changing a single pixel, and a whole batch can go through in one run. Everything happens in an isolated frame of this browser tab, so your pictures are never uploaded, and you can confirm it in the network panel of your browser’s developer tools.

-
PNG without loss
PNG files are repacked with OxiPNG: the file gets smaller while every pixel stays exactly as it was.
-
Batch and ZIP
Drop a folder’s worth of pictures; each one is compressed separately and you can save them together as a ZIP.
-
Metadata left behind
Compressed photos are written without EXIF, so GPS coordinates and camera details do not travel along. The color profile is kept.
JPEG, PNG or WebP: which one to choose
- JPEG is the natural choice for photos: smooth tones compress well and every device opens it.
- PNG suits screenshots, logos and diagrams with sharp edges or a transparent background.
- WebP is usually 25–35% smaller than JPEG at similar visual quality, keeps transparency and opens in every current browser.
Questions and answers
How much smaller will my images get?
It depends on the picture. A phone photo saved at quality 75 often shrinks by 60–80%. Screenshots and graphics kept as PNG usually lose 10–40% with no change to their pixels.
Will compression make my photos look worse?
At quality 70–80 the difference is hard to spot on a screen. Lower levels add visible blockiness, especially in skies and smooth gradients, so look at the result before you send it.
What is the difference between the Fast and Smallest encoders?
Fast uses the encoder built into your browser and finishes in a moment. Smallest uses MozJPEG or libwebp, which squeeze out a few more percent but can take several seconds for a large photo.
Why did my PNG only get a little smaller?
PNG is lossless, so the data can only be packed more efficiently. If the PNG holds a photo, switch the output format to JPEG or WebP under More options for a far smaller file.
Are my images sent to a server?
No. The images are read and compressed on your device, in a frame your browser blocks from using the network. Nothing is uploaded, stored or logged.
Can I compress many images at once?
Yes. Select up to 50 images on a computer or 20 on a phone. Each is processed on its own, and you can download them one by one or as a single ZIP.
