Reduce PNG File Size Online
If you are unable to upload, send, or use your PNG photo due to its large size, ToolsGuru’s PNG Size Reducer allows you to resize it for free on both mobile and laptop—without the need for software installation or registration. It edits the photo directly in your browser using the Canva API, ensuring your image is not uploaded to a server.
How to Reduce PNG File Size Online
You can reduce the size of a PNG image by simply following a few easy steps:
- Upload your PNG — Upload a PNG image from your phone or laptop using the upload button.
- Pick a compression method — You can use the 'Auto' and 'Compress' options here, or manually set the target size.
- Compress the image — The tool keeps your file a PNG and reduces its colour palette until it fits the size.
- Download the result — Check the new (usually much smaller) file size, then download it.
Why Reduce the Size of a PNG Image?
PNG is a lossless format, which is great for graphics and text but means photos and screenshots saved as PNG are often 3-10x larger than they need to be. Reducing PNG size helps with:
- Uploading screenshots to forms or support tickets that reject large files.
- Emailing scanned documents saved as PNG by a scanning app.
- Speeding up a website that's using PNG for photos instead of JPEG.
PNG Size Reducer vs. General Image Compressor
A PNG Size Reducer is focused on helping you make PNG files smaller. A general image compressor may support multiple formats such as JPG, PNG, and WebP and can provide different compression options depending on the file type.
If you specifically have a large PNG and want to reduce its file size, this page is designed for that purpose. If you want to compress different image formats, you can use the Compress Image tool instead.
Need an Even Smaller File?
Very large or detailed PNGs may not reach a small target through colour reduction alone. In that case, use Resize Image to reduce the dimensions, or — if you don't need transparency — use Convert Image to save the PNG as a JPG.
PNG compressor FAQ
How do I reduce the size of a PNG file?
Upload your PNG image to ToolsGuru, select the appropriate compression option, process the image, and download the smaller-sized file. Check the final file size before downloading.
How can I compress a PNG online?
You can compress a PNG online using a browser-based image compression tool. ToolsGuru lets you process your image without installing additional software.
What kind of PNGs work well with this tool?
Screenshots, scanned documents, logos and graphics shrink very well. Detailed photos saved as PNG also shrink a lot, but you may notice slight colour banding at very small sizes.
Can I target an exact KB size?
Yes — switch to "Compress to Size" in the tool and enter a KB target, such as 100KB or 200KB. If a PNG can't get that small, the tool gives you the smallest file it can and suggests reducing the dimensions.
Will this remove transparency?
No. Transparent areas stay transparent, so it is safe to use on logos and graphics that rely on a transparent background.
