ImageSplitCreators publishing on mobile
Shrink a large original before sending it to a social app or moving it between devices.
Image compressor
Use this when a split tool rejects a file over 50 MB, or when email and social forms need a smaller attachment. Desktop allows larger inputs than phones.

What is Image Compressor?
Image Compressor reduces image file size in the browser and shows the result before you download. Use it when a photo is too heavy for a form, message, or social workflow.
How it works
Compress, then continue
- 1
Queue up to 20 images
Files run one after another so a phone is less likely to freeze.
- 2
Set format, quality, and optional caps
Long-edge limits help multi-megapixel camera files. Target size is optional and applies to JPEG and WebP.
- 3
Download and split if needed
Multiple results arrive as a ZIP. Then open a split, print, or PDF page with the smaller file.
Made for real projects
Prepare images for a faster upload or share
Teams sharing assets
Make review files lighter without needing a separate desktop application.
Anyone hitting an upload limit
Try a practical output format and size cap before re-exporting the original artwork.

Tips before you download
Use JPG or WebP for photos
They usually create a smaller result than PNG for photographic images.
Keep PNG for graphics
Text, flat color, and transparent graphics can benefit from PNG.
Compress before splitting large masters
A smaller working file can make a dense mobile grid easier to handle.

Frequently asked questions
Is the compressor free?
Yes. No account, watermark, or quota on the tool itself.
What are the size limits?
About 150 MB on desktop and 80 MB on phones. Split, grid, and PDF tools still cap at 50 MB, so compress first when a master is heavier.
How do I hit 100 KB or 500 KB?
Pick JPEG or WebP, then choose a target size. The tool lowers quality and, if needed, dimensions. PNG ignores the quality slider — use JPEG or WebP when size is the goal.
Will transparency survive?
PNG and WebP can keep it. JPEG flattens onto white. If you need a transparent tile later, stay on PNG or WebP.
Are files uploaded?
No. Compression runs in a local worker. Nothing is stored for training or later retrieval.
