Everyday image tasks, a little lighter.
LightPic brings image compression, format conversion and simple editing into your browser. Prepare photos, website assets and screenshots in one place, while keeping your files on your device.
Less file size, more room
Adjust output quality and dimensions for a batch of images, then compare the results before downloading.
The format you need
Keep the original format or export as PNG, JPEG, WebP or AVIF to suit where your images will be used.
A few finishing touches
Crop, resize and cover sensitive areas with mosaic. Undo or redo edits without changing your original file.
From original to ready, in three steps.
Add your images
Choose image files, drag them here or paste images from the clipboard. You can add several at once.
Adjust and process
Select images and set the output format, quality and size. Open Edit for individual changes, then process the selected images.
Compare and download
Review the size and image comparison. Download results individually or bundle multiple results as a ZIP. Save them before leaving or refreshing.
A few common questions.
Formats, file limits and what happens to your images.
Are my images uploaded to a server?
No. Image processing and ZIP creation happen locally in your browser. Image contents and file names are not sent to the application server. The page still loads the scripts and processing resources it needs.
Which image formats can I use?
LightPic reads and exports static PNG, JPEG, WebP and AVIF images. Animated images are not supported. JPEG does not support transparency; transparent areas become white when exported as JPEG.
Is there a file size or resolution limit?
Each image can be up to 50 MB and 40 million pixels. Large images use more browser memory, so try smaller batches if processing slows down. AVIF encoding can take longer.
Why does a result say “No optimization needed”?
If you only compress an image without changing its format or pixels and the new file is no smaller, LightPic keeps the original only after checking that it contains no sensitive metadata. Otherwise it creates a new file to remove metadata, even if it is larger. Format changes and edits also create a new result.
