Transparency preserved
The full alpha channel survives the resize — no white box behind your logo, no flattened background, no surprises.

Features
Crisp edges, instantly
Lanczos resampling keeps UI lines, text, and icon edges sharp. The PNG engine runs in your browser, so a resize finishes in a blink.
Lossless and watermark-free
PNG output stays bit-for-bit lossless, and your download carries no badge, stamp, or overlay of any kind.
Resize a PNG in three steps
Drop your PNG
Drag a PNG in, tap to pick one on your phone, or paste from the clipboard. It loads instantly and stays on your device.
Set the size
Type exact pixels or scale by percent with the aspect ratio locked. Keep PNG for lossless output or switch to WebP for a smaller file. The preview tracks every change.
Download the PNG
Save the resized PNG with its transparency intact. The original is untouched because it never left your device.
Common PNG resize jobs
Resize a logo with a transparent background
Brand logos ship as transparent PNGs so they sit on any color. Resize one to fit a header or a footer and the transparency stays exactly as the designer intended.
Shrink a retina screenshot for a doc
Screenshots from a high-density display are enormous. Cut one to 1600 wide as PNG and it fits cleanly in an article or a bug report without the text going fuzzy.
Resize an app icon to multiple sizes
Need a 512, 192, and 48 pixel version of the same icon? Resize the master PNG to each size in turn — edges stay crisp at every scale.
Resize a PNG graphic for a slide
Charts, diagrams, and exported graphics often arrive oversized. Fit them to your slide width as PNG and the lines stay readable on the projector.
Resize a sticker or overlay asset
Game sprites, stickers, and UI overlays rely on transparency. Resize them without flattening the alpha so they still composite cleanly over any background.
Resize a PNG for a web upload form
A CMS or marketplace may cap dimensions. Resize the PNG to spec while keeping it lossless, or switch to WebP if the upload also limits file size.
Resizing a PNG the right way
PNG is a lossless format. Unlike JPG it never throws away detail to save space, which is exactly why it is the format of choice for screenshots, logos, icons, and anything with a transparent background. The flip side is that PNGs are larger — so resizing one is usually about fitting it to a layout, not squeezing the file.
Two things go wrong with careless PNG resizers. The first is transparency: flatten an alpha channel against white and your logo suddenly sits in an ugly box. The second is edge quality: a soft resampling filter turns crisp UI lines and text into a blurry mess. AnyResizer preserves the full alpha channel and uses Lanczos resampling so edges stay clean down to the pixel.
Everything runs in your browser on a WebAssembly engine — the PNG stays on your device, so there is no wait and no daily cap. Keep the output as PNG to stay lossless, or switch to WebP for a much smaller file that still supports transparency. You can also resize a whole folder of PNGs at once and grab them zipped.
Why resize PNGs here
- Alpha channel kept fully intact
- Sharp edges with Lanczos resampling
- Optional WebP export for smaller files
- Batch a folder of PNGs at once
Tips for cleaner PNGs
- Tip 1:
Keep PNG output when you need transparency or pixel-perfect lossless quality; switch to WebP when file size matters more — WebP supports transparency too and is far smaller.
- Tip 2:
PNG is the wrong choice for photographs — they balloon in size with no quality gain. Use JPG or AVIF for photos and keep PNG for graphics, screenshots, and logos.
- Tip 3:
Never enlarge a PNG expecting more detail; up-sizing only stretches existing pixels and softens edges. Export from the original vector or master whenever you can.
- Tip 4:
Lock the aspect ratio for logos and icons so they do not stretch. Unlocking is fine for tileable patterns and backgrounds.
- Tip 5:
If your resized PNG feels heavy, run it through the image compressor afterward — PNG compression is lossless, so it shrinks the file with zero quality loss.
Resize PNG FAQ
How do I resize a PNG online?
Drop your PNG into the box at the top, type a width and height or scale by percent, and click download. There is no account, no install, and no plugin needed.
Will resizing keep my PNG's transparency?
Yes. The full alpha channel is preserved through the resize, so transparent areas stay transparent. There is no flattening against a background color unless you deliberately convert to a format like JPG that has no transparency.
Can I resize a PNG without losing quality?
Yes. PNG is lossless, so keeping the output as PNG means no quality is lost in re-encoding. Downscaling reduces pixel count, but Lanczos resampling keeps the result as sharp as the smaller size allows.
Is my PNG uploaded to a server?
No. The engine runs in your browser with WebAssembly, so the file never leaves your device. You can verify nothing is sent in your browser's Network panel.
Why is my PNG so large, and how do I make it smaller?
PNGs are large because they are lossless. After resizing, run the file through the image compressor for lossless size reduction, or switch the output to WebP for a much smaller file that still supports transparency.
Can I resize a PNG and convert it to JPG?
Yes, but JPG has no transparency, so any transparent area is filled with a background color on export. If your PNG has no transparency, converting to JPG is a fine way to shrink a photographic image.
Will my resized PNG have a watermark?
Never. The output is your resized PNG with no overlay, badge, or metadata stamp. The tool is free with no freemium tier, so there is nothing to watermark.
Can I resize several PNGs at once?
Yes. Drop multiple PNGs, apply one size, and download the whole batch as a ZIP in a single pass.
