Preserve detail
Use 85-92% quality for product images or photos where fine detail matters.
Web-ready balance
WebP at 70-82% and a 1600-2560 pixel limit works well for most websites.
Smaller attachments
Use 55-70% quality and reduce dimensions for email or strict upload limits.
Format notes
JPEG, WebP or PNG?
JPEG
Broadly compatible and efficient for photographs; transparency uses the selected background.
WebP
Usually smaller than JPEG at similar visual quality and can preserve transparency.
PNG
Lossless and useful for graphics or transparency; quality and target-size controls do not apply.
Image compressor FAQ
Are my images uploaded?
No. Files are processed locally with browser APIs.
Can I target an exact file size?
The tool searches JPEG or WebP quality levels and aims to stay below the requested size.
Why can output be larger?
The source may already be optimized, or the chosen format and quality may need more bytes.
Is metadata preserved?
No. Canvas export generally removes EXIF, GPS and camera metadata.
