Asset standardization
Use it when a batch of images needs to share the same dimensions before import into a game, app, or asset pipeline.
Tool
Resize images online in batches
Drop in one or many images, set a fixed width and height, then export resized PNG outputs from the browser without switching apps.
Quick Answer
How to resize images online in batches
To resize images online in batches, upload one or more files, enter the target width and height, run the resize process, then download the PNG results. This tool is best when you need consistent dimensions before moving assets into pixel conversion, spritesheet assembly, or layout work.

How To
Resize images in four steps
- Upload one image or batch-upload many images into the resizer.
- Set the target width and height values that every output should follow.
- Run the batch resize to generate standardized PNG outputs.
- Download the files and move them into the next step of your asset workflow.
Best For
When the Image Resizer is most useful
Pre-processing before pixel work
Use it before the Pixel Art Converter when source files are inconsistent and need a cleaner starting size.
Preparation before sheet assembly
Use it before the Spritesheet Generator when frames need consistent width and height.
Tool Choice
Image Resizer vs Pixel Art Converter
Use Image Resizer
Choose this tool when you need exact width and height control and want to standardize dimensions across many files.
Use Pixel Art Converter
Choose the Pixel Art Converter when you want a retro pixel-art look rather than only dimension changes.
Use both in sequence
Resize first to clean up inconsistent sources, then convert to pixel art if the final asset needs a retro-style output.
Next Step
What to do after resizing images
- Open the Pixel Art Converter if the resized files should become pixel-style sprites, icons, or props.
- Open the Spritesheet Generator if the resized files are animation frames that need one PNG atlas.
- Open the 2D Tile Map Editor if the resized assets are heading into map or tile-placement workflows.

FAQ
Common questions about the Image Resizer
What does the Image Resizer do?
It batch-resizes uploaded images to fixed width and height values and exports PNG outputs directly in the browser.
Can I resize multiple images at once?
Yes. The tool is built for batch processing, so it works well when you need to standardize many files quickly.
When should I use it before other Pixel Tools pages?
Use it when you want consistent dimensions before moving assets into pixel conversion, spritesheet generation, or another step in your pipeline.
How do I resize images online in batches?
Upload the images, set the output width and height, run the batch resize, then download the PNG outputs. This is the fastest way to standardize many files in one pass.
When should I use Image Resizer instead of Pixel Art Converter?
Use the Image Resizer when you need fixed dimensions without changing the overall visual style. Use the Pixel Art Converter when you want a retro pixel-art result.
What should I do after resizing images?
Move the files into the Pixel Art Converter, Spritesheet Generator, or 2D Tile Map Editor depending on whether the next step is pixel styling, animation sheet assembly, or layout work.
