## About

Compress a JPG, PNG, or WebP below the 1MB line that portals, email, and hosting love to draw — done locally.

## Quick answer

How do I compress an image to 1MB? Drop your image, select the 1 MB target, and download. The compressor only reduces quality enough to fit under 1 MB, and the file never leaves your browser.

## How to compress an image under 1 MB

1. **Add the oversized image** — typically a modern phone photo or an uncompressed export.
2. **Pick the 1 MB target** — quality reduction alone usually does the job; dimensions stay intact.
3. **Download** — near-original appearance, a fraction of the weight.

## Why 1MB keeps coming up

- Email and messenger attachment hurdles
- Government and company portals that cap single images at 1–2 MB
- Website and app backends with per-image limits

## Good to know

If your file is already under 1 MB, you do not need to compress it — check with [Image info](https://toolpantry.app/image-info.html) first. At this budget, visible quality loss is rare; any slight softness usually comes from the photo being upscaled somewhere in the pipeline.

## Notes

Target sizes are approximate ceilings. Very detailed images may need a smaller resolution to fit while staying readable.

## FAQ

**Why did the dimensions change?**

When quality alone cannot reach the target, the compressor gently reduces the pixel dimensions so the file becomes small enough to send or upload.

**Will the original be overwritten?**

No. The result is a new downloaded file. Your original remains unchanged on your device.
