Use Exact Pixels When You Have a Required Size
Enter a width and height when a website, interface, or document specifies the final dimensions. With proportions locked, changing one value calculates the other from the original icon.

How to Resize an Icon Online
Choose one local icon, set a meaningful size, keep the original shape, then check the actual PNG before downloading it.
- Step 1
Choose One Icon File
Choose, drop, or paste one PNG, JPG, or WebP icon. Keep the original file so you can create another size later.
- Step 2
Set Pixels or a Percentage
Enter the exact width and height you need or use a percentage. Keep proportions on unless you deliberately want to stretch the icon.
- Step 3
Compare, Check, and Download
Review the Original and Resized PNG on the background where it will be used, confirm the output dimensions, then download the result.
Resize an Icon to Exact Pixels or a Percentage
Use exact width and height when a destination gives you a requirement. Use a percentage when you need the same icon at a smaller or larger scale.
Use a Percentage for Proportional Scaling
Choose a percentage for a relative change, such as a half-size UI icon. The output dimensions are calculated from the source file you selected.
Start With a Common Square Size, Then Verify It
Square shortcuts are useful starting points for common icon tasks. Confirm the destination's current requirements before treating any preset as a final platform specification.
Keep Your Icon's Shape and Transparency
An icon can look correct at a large size and fail at its final size. Protect its proportions, transparent edges, and visible contrast before you download.
Keep Proportions On Unless Distortion Is Intentional
Leave the proportion lock on for logos and interface icons. Unlock it only when the destination truly needs independent dimensions and you have checked that stretching is acceptable.
Use a Square Source for a Square Result When Possible
Resizing changes pixels; it does not remove empty space or intelligently compose a non-square image into a square. Use a square source, or crop and review the composition in a tool that actually supports cropping.
Check Transparent Edges on Light and Dark Backgrounds
Review the Original and Resized previews on a checkerboard, a light surface, and a dark surface. Thin strokes, halos, and low-contrast details are easier to spot before export.
Review the Resized Icon Before You Download
Use the result details and side-by-side preview to confirm that the file you download is the file you intended to make.
Compare the Original and the Resized Icon
Keep both previews visible after processing so you can compare the full shape, transparent edges, and small details without losing the source reference.
Confirm the Output Dimensions and Format
The result summary shows the original and output width, height, format, and file size. File size depends on image content and encoding, so it may not change in direct proportion to dimensions.
Check the Icon at Its Intended Small Size
A 16px or 32px icon can lose thin lines and tiny text even when a larger preview looks fine. Inspect the selected output size and simplify the source when the mark is no longer recognizable.
Choose the Right Icon Workflow
Resize one icon file here when you need a specific raster output. Use a different workflow only when your job requires a file container, a platform package, a vector edit, or an operating-system setting.
Resize One File or Create an App Icon Package?
This page exports one resized PNG. A complete iOS, Android, or desktop package needs multiple sizes, file names, and sometimes manifests; use a tool that genuinely creates the full package when that is your task.
ICO and SVG Need Their Own Supported Workflow
ICO can contain multiple embedded sizes, and SVG is vector artwork rather than a raster pixel grid. This page accepts raster PNG, JPG, and WebP files only; it does not edit ICO or SVG files.
Changing Desktop Icon Size Is a Different Task
This tool resizes an image file. It cannot change the size of icons displayed by Windows, macOS, iPhone, or Android; use the device's display or home-screen settings for that task.
Common Single-Icon Tasks
These examples describe one-file resize jobs. They are decision aids, not claims that a downloaded file automatically meets every platform's current submission rules.
Make a Smaller Website or Favicon Asset
Start from a clean, high-resolution source, choose the exact single-file size your website workflow requests, and inspect the icon at that small result size before download.
Prepare a UI Icon for a Fixed Layout
Use exact pixels when a design system or interface slot has a fixed width and height. Keep proportions locked unless the icon was designed for independent stretching.
Create a Review Copy Before a Platform Package
Use one resized PNG to review shape and contrast. When a store or app build needs many assets, move to a verified packaging workflow instead of assuming one download covers every required file.
Formats, Local Processing, and Limits
Make the supported input formats, output format, practical size limits, and processing location visible before you choose a file.
Supported Files and PNG Output
Choose one PNG, JPG, or WebP input file. This tool downloads a PNG, which can retain transparent pixels from a transparent source image.
Processed in Your Browser
The selected icon is decoded, resized, previewed, and exported in the current browser tab. No account is required, and the page does not send the source image or result to an external image-processing service.
Practical Limits and Honest Quality Notes
This tool processes one file at a time up to 10 MB and 8,000 pixels on either side. Shrinking removes pixels, while enlarging can look softer because ordinary resizing cannot create missing source detail.

Icon Resizer FAQ
Direct answers about pixels, proportions, transparent PNG output, supported files, desktop icon settings, and free browser-based use.
How do I resize an icon to exact pixels?
Upload one supported icon, choose Exact pixels, enter the target width and height, and leave Keep proportions on if you want the other value to update with the source aspect ratio. Select Resize icon, review the PNG result, and download it.
Can I resize an icon without stretching it?
Yes. Keep the aspect-ratio lock enabled to calculate the other dimension from the source icon. Unlock it only when independent width and height are intentional, because resizing to a different ratio stretches the image; it does not crop or recompose it.
Will PNG transparency stay transparent after resizing?
The tool exports PNG, which can retain transparent pixels from a PNG or WebP source. Check the Original and Resized previews on the checkerboard, light, and dark backgrounds before download. A JPG source has no transparent pixels to preserve.
Can I resize an ICO file or make a multi-size ICO?
No. This focused tool accepts PNG, JPG, and WebP images and exports one PNG at a time. It does not read or write ICO containers, create a multi-size ICO, or generate a ZIP package.
Can I resize an SVG icon here?
This page resizes raster image pixels and does not edit SVG files. Convert an SVG to PNG first if you need a raster PNG version, then resize that output to the dimensions you need. Keep the SVG master when you need a scalable vector source.
Can this change the size of icons on my desktop or phone?
No. This tool changes the pixel dimensions of an image file. Windows, macOS, iPhone, and Android icon display sizes are controlled through each device's own settings.
Is the icon resizer free and do I need to sign in?
This icon resizer is free to use online with no registration or login. It processes one supported image in the current browser tab and lets you download the PNG result.
