Image compressor

Reduce the size of a photo for email or an online form. The tool adjusts JPEG quality first and may reduce pixel dimensions to reach the target. Always check small text and important details in the downloaded result.

Useful for

• Send smaller email attachments
• Meet an online form's image size limit
• Reduce website image size while preserving useful detail

How to use it

1. Choose a JPG, PNG or WebP image
2. Select a target size or enter a custom value
3. Check output size, dimensions and clarity before downloading

Singapore example: Preparing a school form attachment

Suppose a form requires each image to be smaller than 1MB. Try a custom 800KB target, then inspect the actual downloaded size and small print.

800KB is an illustrative margin, not a universal school requirement. If the original already meets the limit and is clear, it may need no compression.

Things to check

• Output may be smaller than the target rather than exactly equal
• Transparent areas become white in JPEG output
• Very small files can make text hard to read
• Keep the original and inspect the download at full size

Frequently asked questions

Why did the pixel dimensions change?

When quality adjustment is insufficient, the tool gradually reduces image dimensions.

Can I choose less than 20KB?

The minimum target is 20KB to limit severe quality loss.

Will the original be overwritten?

No. The tool creates a separate download.

Does it accept HEIC?

It directly accepts JPG, PNG and WebP. Convert HEIC to a supported format first.
