Frequently Asked Questions

What format is best?

For photos, use JPG (smaller size). For logos or text, use PNG (crisp quality). For web usage, WebP is the best balance.

Is it free?

Yes, PhotoEditOnline is completely free to use for unlimited image resizing.

Why did my image get blurry?

If you make an image significantly larger than its original size, it may become blurry. It's best to start with a high-resolution photo.

How do I resize an image to 1080x1080?

Open the Resize tool, upload your photo, go to Image > Resize, and type 1080 in both Width and Height fields. Ensure 'Maintain Aspect Ratio' is unchecked if your original image isn't square.

What's the best size for Instagram photos?
Instagram posts work best at these dimensions:
  • Square Posts: 1080 x 1080 px (1:1)
  • Portrait: 1080 x 1350 px (4:5)
  • Landscape: 1080 x 608 px (1.91:1)
Use our resize tool to set these exact dimensions.
Does resizing reduce image quality?

Scaling down (making it smaller) usually keeps quality high. Scaling up (making it larger) may cause pixelation, but our tool uses advanced resampling to minimize quality loss.

How to resize images for web without losing quality?

For web use, resize to the exact display dimensions (don't make larger than needed). Our tool maintains quality when downsizing using professional resampling algorithms.

Can I resize multiple photos at once?

Currently, PhotoEditOnline focuses on single-image editing to ensure maximum privacy and control. You can process images one by one very quickly.

What's the difference between resize and compress?

Resizing changes image dimensions (width x height), while compressing reduces file size. You can resize without changing file size, or compress without changing dimensions.

How to resize images for printing?

What file formats can I resize?

PhotoEditOnline supports resizing JPG, PNG, WebP, and PSD files. All processing happens locally in your browser for privacy.

How to resize images for YouTube thumbnails?
