Resize Image — Free, Fast & Private
MiniPx makes resizing images simple. Set exact pixel dimensions, resize by percentage, or choose from preset sizes for social media, web, and print. The aspect ratio is maintained automatically unless you choose to override it.
Resizing works hand-in-hand with compression. A 4000x3000 photo from your phone is far larger than most uses require. Reducing dimensions to 1920px, 1280px, or 800px dramatically cuts file size while keeping images sharp enough for screens, uploads, and documents. That is the shrinking direction; to go the other way and make a small image larger without pixelation, use the image enlarger, which fills in the missing pixels with AI rather than stretching the existing ones.
Common resizing needs include: reducing photos for email attachments, hitting exact dimensions for website headers, preparing images for social media posts, and meeting upload requirements for government forms and job portals.
MiniPx processes everything client-side. Your photos never leave your device — particularly important when resizing personal documents, ID photos, and passport images.
For batch resizing, add multiple images and apply the same dimensions to all of them. Download individually or as a ZIP archive.
