Frequently asked questions
How much smaller will my photo get?+
Smartphone camera photos typically shrink by 70–90% — a 5MB photo becomes a few hundred KB. PNG screenshots also shrink dramatically when compressed to JPG.
Will it look much worse?+
'Recommended' is hard to tell from the original on screen. For forum attachments, chat and email, even 'Strong' looks fine; use 'High quality' for photos you'll print or archive.
Are my photos uploaded to a server?+
No. Compression happens entirely inside your browser and your photo is never sent anywhere.
Which formats are supported?+
HEIC, JPG, PNG, WebP, AVIF, GIF and BMP as input; the result is saved as JPG for maximum compatibility.
When do I need this?+
When you hit a photo size cap on an application or submission site (often 100KB–1MB), an email attachment limit, a forum upload limit, or want to free up phone storage.
Why did the pixel dimensions change too?+
'Strong' and 'Recommended' also cap the long edge at 1600px and 2560px respectively — plenty for screens and the web, and necessary for real size savings. Choose 'High quality' to keep the original resolution.
Guide
What decides a photo's file size?
Two things: resolution (pixel count) and compression quality. Modern phone photos are 4,000×3,000 pixels (12MP) and weigh 3–10MB each — yet screens look perfectly sharp at half that resolution.
Effective compression therefore does both: scale the image to a screen-appropriate size, and tune the compression quality to just below what the eye notices. That combination is exactly what the 'Recommended' setting does.
How to pick a compression level
'Recommended' is the right default — long edge capped at 2560px, quality 70%. For anything viewed on a screen it's nearly indistinguishable from the original at a fraction of the size.
For 'smaller is better' uses — chat apps, email, forum attachments — go 'Strong'. Reserve 'High quality' for photos you'll print or want at original resolution.
When is this useful?
Upload limits are the most common reason: ID photo caps on application portals (100KB–1MB), email attachments (25MB) and community forum limits all become passable after compression.
It also pays off for blogs and online shops — lighter product images make pages load faster, which keeps visitors around and helps search rankings.
