Resize Image Online — Free, Fast & Private

Whether you need to resize photos for a website, social media, email, or document upload, MiniPx makes it fast and simple. Set a maximum width and MiniPx automatically scales the image proportionally — no distortion, no cropping.

MiniPx offers three preset sizes: 1920px (full HD, ideal for websites and presentations), 1280px (great for email and social media), and 800px (compact, ideal for form uploads and thumbnails). The aspect ratio is always preserved.

You can also combine resizing with format conversion and compression. For example, resize a 4000px PNG to 1280px WebP with Smart compression — reducing both dimensions and file size in one step.

How it works

  1. Upload your image: Add the image you want to resize.
  2. Choose max width: Select 1920px, 1280px, or 800px depending on your needs.
  3. Optional: change format: Convert to WebP, JPEG, or PNG during the resize.
  4. Download resized image: Save the resized file — aspect ratio is preserved automatically.

Frequently asked questions

Does resizing change the aspect ratio?
No. MiniPx scales images proportionally. If you set max width to 1280px, a 4000x3000 image becomes 1280x960 — same ratio, smaller dimensions.
What max width should I use?
1920px for websites and presentations, 1280px for email and social media, 800px for form uploads and thumbnails. When in doubt, 1280px is a safe general-purpose choice.
Can I resize and compress at the same time?
Yes. MiniPx resizes and compresses in one step. This is the most effective way to reduce file size — combining dimension reduction with quality compression.
Can I resize multiple images at once?
Yes. Add multiple images and they will all be resized to the same max width. No file limits.
