Check the size report
The result summary compares total input and output size and tells you how many images missed the target.
Download the results
One image downloads directly. Multiple images are packaged as a ZIP, and your original files stay unchanged.
Compress images: three ways compared
The main differences are installation and file handling.
| What matters | AmiIMG online | Desktop editor | Browser extension |
|---|---|---|---|
| Cost | Free | Varies by product | Varies by extension |
| Install | No install | Required | Extension required |
| Batch of 50 | Supported | Depends on the editor | Depends on the extension |
| Target size | Exact per-image target | Varies by product | Varies by extension |
| File handling | Local in your browser | Usually local; check the editor | Check whether files are uploaded |
Where 500KB shows up
Three common reasons to reduce image file size.
Meet an upload limit
When a form caps each image, compression aims to land every file at or under the cap — the summary flags any that miss it.
Prepare images for a page
Reduce large JPG or PNG assets before publishing. Choose the quality level that fits each image.
Send a batch of photos
Process up to 50 images in one batch. Multiple results download together as a ZIP.
Store-speed friendly
E-commerce platforms often cap listing images at 500KB to protect page speed. Bulk-resizing a catalog under that line keeps listings live.
Private by design
Every operation runs inside your browser. Your images are never uploaded anywhere.
Batch up to 50 images
Add up to 50 images, each up to 30MB. Multiple results download as one ZIP.
Lands under the limit
Target mode tunes quality image by image until each file fits, and says so when one can't get there.
Free & unlimited
No accounts, no daily caps, no watermarks stamped on your files. Ever.
Batch that respects the line
Fifty images per run, each judged on its own against the cap — one oversized photo can’t break the batch.
Compressing to 500KB — FAQ
What does 500KB mean here?
The binary convention: 500KB = 512,000 bytes. Every exported file lands at or under that size, or you get the closest possible result with a clear notice.
Is the target per image or for the whole batch?
Per image. Each file in the batch is compressed to the target on its own; a ZIP of results can be larger.
Do PNG files stay PNG?
No. Target compression needs a quality dial, so PNG (and GIF/BMP) sources export as JPG. JPG and WebP keep their format.
Are my images uploaded to a server?
No. Compression runs entirely in your browser — your images never leave your device.
Edit a batch of images in one workspace
Rotate, crop, watermark, remove backgrounds, collage — drag all your images in and export in one go.
