Click to upload or drag & drop a photo
Processed entirely in your browser — nothing is uploadedKB or MB — which should you use?
If your form states a limit under 1000KB, our KB-based compressor is a more precise fit; this page is for limits stated directly in megabytes, common for larger uploads like scanned multi-page documents or high-resolution photo submissions.
How to use Reduce Image Size in MB
- Click the upload area and choose the photo you need to shrink (or set your own target if the page has a target-size field).
- Wait a moment while the tool tries different quality levels to find the best result under your limit.
- Check the before/after preview and file size shown on screen.
- Press the download button to save the compressed file to your device.
Tips for best results
- Start from the highest-quality original you have — compressing an already-compressed file gives worse results than compressing the source photo once.
- If your form gives a size range rather than a hard limit, aim for the upper end for the clearest result.
- JPEG compresses photographs far better than PNG — if you're starting from a PNG screenshot of a photo, expect a bigger size drop than usual.
❓ Frequently asked questions
Do I need to install anything to use this?
No — everything runs directly in your browser using standard web technology; there's nothing to download or install.
Will this work on my phone?
Yes — the tool works on any modern mobile browser the same way it does on desktop.
What's a typical MB limit I might see?
Limits like 2MB, 5MB, or 10MB are common for general document and photo upload portals that aren't as size-conscious as government exam forms.
Can I type a decimal, like 1.5MB?
Yes — the input accepts decimal values for precise targets between whole megabytes.
Should I use this or the KB tool for a 500KB target?
For anything under 1MB, our KB compressor gives more precise control.
