Resize a PNG logo without stretching
Keep aspect ratio enabled to preserve the original proportions of logos, icons and transparent brand assets.
Resize PNG vs compress PNG
Resize changes width and height. Compression targets file size in KB or MB without requiring new pixel dimensions.

Resize PNG images by pixels without losing transparency
Resize PNG by pixels
Enter an exact width and height or start from quick widths such as 256, 512, 1024 or 1920 pixels. Lock the aspect ratio when you want the height to update automatically.
Resize a PNG logo without stretching
Keep the original proportions for logos, icons and transparent assets. The PNG alpha channel remains intact, so transparent backgrounds stay transparent.
Resize PNG vs compress PNG
Resizing changes pixel dimensions. Compressing reduces file size without necessarily changing width or height. Use the PNG Compressor when your goal is a smaller file rather than a smaller image.

FAQ
Common questions
How do I resize a PNG by pixels?
Upload the PNG, enter the exact width and height you need, or choose a quick pixel width such as 256, 512, 1024 or 1920 pixels. Keep aspect ratio enabled if you want the other dimension calculated automatically.
Can I resize a PNG logo without losing transparency?
Yes. The output remains PNG and the resize canvas keeps the alpha channel, so transparent logo backgrounds and transparent pixels remain transparent.
How do I resize a PNG without stretching it?
Keep the aspect-ratio option enabled. Changing one dimension then updates the other proportionally so the image is not distorted.
Does resizing a PNG reduce its file size?
Reducing pixel dimensions often reduces file size, but resizing and compression are different operations. If you want fewer KB or MB without changing width and height, use the PNG Compressor.
Can I make a PNG larger?
Yes. You can increase its pixel dimensions, but PNG is a raster format, so enlarging it cannot create new image detail and may make edges or photos look softer.
What is the difference between PNG dimensions and file size?
PNG dimensions are the image width and height in pixels, such as 1200 × 800. File size is the amount of storage the file uses, such as 450 KB or 2 MB.
Is my PNG uploaded to a server?
No. The supported resize flow processes the PNG locally in your browser.
