They never leave your browser — compression runs locally
80% is the sweet spot for most photos. Lower for faster page loads.
When to compress to 5 MB
Email attachments (most providers), high-resolution online uploads.
Common file-attachment limit. Photos can stay at full resolution with minor JPG compression.
How it works (5 steps)
- Drop your image. Drag a JPG, PNG, or WebP onto the drop zone above. Multiple files are compressed in parallel.
- Tool pre-locks the ${t.label} target. The tool is already set to compress to 5 MB. You don't need to set anything.
- Tool runs binary search. Internally the tool tries JPG quality 50%, then narrows to 75% / 25% / etc. until output lands within 5% of 5 MB. Usually 3-5 passes per image.
- Compare and download. Click "Compare" to see a before/after slider. Download the compressed file as JPG.
- Upload to wherever needs it. Submit the compressed image to whichever portal requires the 5 MB cap.
What if my source image is too large?
If your source is over ~5 MP and quality compression alone can't hit 5 MB, the tool also downscales the dimensions. You can set a max-width cap if you want to control how much it shrinks.
Frequently asked questions
+−How do I compress an image to exactly 5 MB?
Use the tool above in target-size mode (already pre-locked to 5 MB). Drop your image and the tool runs binary search across JPG quality levels until output lands within 5% of 5 MB. Usually 3-5 passes.
+−Will the image quality drop noticeably at 5 MB?
Common file-attachment limit. Photos can stay at full resolution with minor JPG compression. For larger source images, the tool also reduces dimensions if needed to hit the target.
+−Is the 5 MB compression done in the browser?
Yes. Compression runs entirely in your browser using the Canvas API. Your image never leaves your device — useful for sensitive documents like ID photos or signed contracts.
+−Why does my image need to be exactly 5 MB?
Common reasons: Email attachments (most providers), high-resolution online uploads.. Most online forms reject uploads outside the size range, so hitting the exact target matters.
+−Can I batch compress many images to 5 MB?
Yes — drop as many as you want into the tool, all are compressed in parallel. Download individually or as a ZIP.
+−What format will the output be?
Default output is JPG (smallest for photos). You can switch to WebP for ~30% smaller files, or PNG for lossless (rarely matches the size target).
