How to compress an image to 1MB
The most common attachment cap in email, handled in one pass.
Add your images
Drag and drop, or click to browse. Up to 50 images per batch.
1MB per image
Photos are compressed to about 1MB each — enough quality for viewing, small enough to send.
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 |
|---|---|---|---|

| 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 |
Hitting 1MB limits
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.
The 1MB ceiling
Webmail services and many corporate mail servers reject attachments once they pass 1MB. It is the single most common cap people hit.
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.
Quality kept where it shows
The search lowers quality only as far as needed, so photos stay viewable instead of being crushed flat.
Compressing to 1MB — FAQ
What does 1MB mean here?
The binary convention: 1MB = 1,048,576 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.
Is there a limit?
Up to 50 images per batch, each up to 30 MB.
Edit a batch of images in one workspace
Rotate, crop, watermark, remove backgrounds, collage — drag all your images in and export in one go.
