How it works
Choose an image (or drag it in, or paste it with Ctrl+V), set the new dimensions and quality, press Apply and download the result. Everything happens in your browser using your device's own drawing functions: the photo is never uploaded to a server, so it works offline too and is safe for documents and personal photos.
Resizing: which option to pick
- Longest side: the simplest way. Set how many pixels the longer side should have (1600 for email, 1200 for a website, 1080 for social media) and the proportions stay the same.
- Width or height: when a form requires an exact measure, for example 600 px wide.
- Percentage: to halve (50%) or quarter (25%) any image.
Modern phone photos are 4000 × 3000 pixels or more: for screens and the web 1200-1600 is plenty, and weighs ten times less with no visible difference.
Compressing: format and quality
JPG is the right format for photos: at quality 80-85 the eye sees no difference and the file shrinks a lot. WebP is about 25-30% smaller than JPG at the same quality and is supported by all recent browsers. PNG is lossless and keeps transparency: perfect for logos, screenshots and graphics, but heavy for photos (the quality slider has no effect on PNG).
Common size limits
Government forms and job applications often require photos under 1 MB or 500 KB; many portals accept 2 MB at most; ID photos have precise formats (for example 35 × 45 mm, 413 × 531 px). With a 1200 px longest side and quality 80, a 5 MB photo usually drops below 300 KB.
Frequently asked questions
Are my photos uploaded anywhere?
No. Processing happens in the browser, on your device: you can use the tool even without a connection.
How do I get a photo under 1 MB?
Set "Longest side" to 1600 px, format JPG and quality 80, then press Apply: the caption shows the new size. Lower the quality or dimensions if needed.
Why does PNG stay heavy?
PNG is a lossless format: quality has no effect. For photos choose JPG or WebP; use PNG only for graphics, logos and images with transparency.
