How to use this tool

Choose a JPEG, PNG or WebP file, or drag it onto the drop area.
Check the target size (currently 1 MB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool lowers the quality first, then reduces the dimensions step by step if the file is still too large.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you reduce Image Size in MB

Phone and camera photos are often between 3 and 10 MB, which is more than many email systems, chat apps and upload forms allow. Reducing a photo to 1 or 2 MB almost always leaves it looking the same on a screen, because most of the extra data in a large photo is detail that a phone display cannot show. The tool does this in two steps: it lowers JPEG quality a little, and if the file is still too large it scales the pixel dimensions down. The saved file is measured, so the size you see is the size you get. If your limit is stated in KB rather than MB, remember that 1 MB equals 1,024 KB, so 2 MB is 2,048 KB. Pictures that are already small or already heavily compressed may not shrink much, because there is less data left to remove.

Megabyte limits are common for uploads, email and messaging. Phone photos are often 3 to 8 MB, so a light squeeze is usually enough. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

Use JPEG output for photographs. Start at 1 MB and raise it to 2 MB if you want more detail. For a screenshot or a graphic with sharp text, PNG keeps edges clean but shrinks less, so JPEG is the better route when the limit is tight.

Accepted input: JPEG, PNG and WebP (WebP depends on your browser). HEIC and AVIF are not supported. PNG is lossless, so it can only get smaller with fewer pixels unless you choose JPEG or WebP output.

Practical uses

Sending photos by email or messaging without hitting the attachment cap
Uploading to a portal that allows only a few MB
Saving space on a drive or a website

Tips for a smaller file

A 1 MB photo is plenty for screen viewing; keep the original for printing.
Reduce once from the original, not repeatedly from a reduced copy.
For a very small limit in KB, use the KB size pages instead.

Frequently asked questions

How do I reduce a photo from 5 MB to 1 MB?

Choose the photo, leave the target at 1 MB and start. The tool lowers quality and, if needed, dimensions, then shows the real size.

Will the picture look worse?

Usually not on a screen. Going from several MB to 1 or 2 MB removes detail that most displays cannot show.

Is anything uploaded?

No. The file is processed in your browser and never leaves your device.
