Resize PNG graphics and screenshots

PNG works well for interface graphics, logos, diagrams, and screenshots. When the source contains transparency, PNG output keeps the transparent areas instead of replacing them with a solid background.

PNG file size

PNG uses lossless compression, so detailed photographs can be much larger than equivalent JPG or WebP files. Reducing dimensions lowers the number of pixels and can significantly reduce the resulting file size.

How to use this tool

Frequently asked questions

Will PNG transparency be preserved?

Yes. Selecting PNG output preserves transparent areas when the browser resizes the image.

Are my images uploaded anywhere?

No. Resize.Tools processes supported images locally in your browser. The image does not need to be sent to a Resize.Tools server.

Does resizing reduce image quality?

Reducing dimensions normally preserves a clean appearance, while enlarging an image can reveal softness or pixelation. JPG and WebP quality settings can also affect detail and file size.

How do I resize without stretching the image?

Keep Lock aspect ratio selected for a normal resize. For an exact frame with different proportions, choose Fit inside to keep the entire image visible or Crop to fill to cover the frame.

How does crop positioning work?

Crop to fill keeps the output proportions and removes excess image area. Use a quick position or the horizontal and vertical sliders to decide which part stays visible.
