Frequently Asked Questions

How do I resize an image online?

Upload your JPG, PNG, or WebP images, choose the resize settings, process the batch, and download the resized files in one ZIP.

Can I keep the original aspect ratio?

Yes. Keep the aspect ratio option enabled to prevent the image from being stretched when you change one dimension.

Can I resize multiple images at once?

Yes. QuietPDF supports batch image resizing and returns the completed files in one ZIP download.

Which image formats are supported?

The image resizer supports JPG, PNG, and WebP input files.

Will resizing make my image blurry?

Making an image much larger can soften detail. For the clearest result, resize close to the original dimensions and avoid repeated enlargement.

When to use this tool

Change image dimensions for forms, profiles, websites, and email while preserving the original file. Resize first when pixel dimensions, rather than format alone, are causing an upload problem.

A portal requires a specific width, height, or maximum pixel dimension.
Camera photos are far larger than their intended on-screen display size.
Several images need consistent dimensions for a document or website.

Tips for best results

Keep aspect ratio enabled unless the destination requires exact dimensions that may crop or stretch the image.
Avoid enlarging small images significantly because resizing cannot recreate missing detail.
Check text and logos in the resized result before using it in a form or publication.

Privacy and file retention

The selected images are temporarily decoded and resized for this request. Inputs and resized outputs are scheduled for deletion within the short 30-minute retention period; the original files on your device are not modified.
