About Resize Image

Resize image files for a website that wants them 1920 pixels wide, a shop listing with square photos, or a YouTube thumbnail at 1280 × 720. Choose how: exact pixels, a percentage, or one of eight social media sizes, from an Instagram story to a WeChat article cover and a Xiaohongshu post. When the file size matters rather than the dimensions, Compress Image is the tool to use.

In pixel mode, fill in the width and leave the height at 0 to keep the proportions, or set both and the picture fits inside that box. For social sizes, open More options and pick Fit inside to add a background color around the whole picture, Fill and crop to cover the frame, or Stretch. Animated GIFs stay animated, and HEIC photos from an iPhone come back as JPG.

Why use Cubfile for this

  • Three ways to resize

    Exact width and height, a scale from 1% to 400%, or a named preset such as Facebook cover 820×312.

  • Proportions protected

    Keep aspect ratio is on by default, so faces and logos never get squashed unless you turn it off.

  • Eight social media presets

    Instagram post and story, Facebook cover, X post, YouTube thumbnail, LinkedIn post, WeChat cover and Xiaohongshu.

  • Sharp downscaling

    Pictures are resampled with the Lanczos filter, which keeps edges and text crisp when you make them smaller.

FAQ

Resize Image: questions and answers

How do I resize an image without stretching it?
Leave Keep aspect ratio ticked. Enter only the width with height 0 and the height follows, or enter both and the picture fits inside that box without distortion.
Can I resize an image to make it bigger?
Yes, up to 400% or 20,000 pixels on a side. Enlarging doesn't add detail, though, so a small photo will look soft when blown up.
What happens to a photo that doesn't match the social media size?
It depends on Fit. Fit inside keeps the whole picture and fills the gap with your background color, Fill and crop covers the frame and trims the edges, and Stretch forces the picture to the size. Cropping first with Crop Image at the right ratio lets you choose exactly which part stays.
Can I resize images in bulk for free?
You can. Visitors have 2 tasks in total and free accounts 2 per day, for files up to 50 MB. VIP removes the daily cap, allows files up to 1 GB and resizes up to 50 images per task.
What happens to my files after resizing?
They're kept for one hour so you can download them, then deleted automatically. Uploads use HTTPS, every task runs in its own process, and nobody looks at your pictures.
