Frequently asked questions
How do I resize an image without stretching it?
Keep the aspect ratio locked. The tool then calculates the matching height for your chosen width (or vice versa), so proportions stay correct.
Does resizing reduce image quality?
Scaling down keeps images sharp. Scaling up cannot add detail that was never captured, so enlargements beyond about 150% may look soft.
What sizes do social platforms use?
Common targets: 1080×1080 for Instagram posts, 1200×630 for link previews, 1280×720 for YouTube thumbnails, and 400×400 for most profile photos.
Is there a file size limit?
No fixed limit — processing happens on your device, so the practical limit is your browser's memory, which comfortably handles photos from any modern camera.
