PNG Compressor - Reduce PNG File Size Online

Our PNG compressor is a great utility tool that can reduce the file size of your PNG images to any size that you like. It uses efficient lossy compression algorithms that minimize data loss during the size reduction. As such, the PNG image quality is maintained quite well. However, that can change if you do extremely drastic compressions.

How to Compress PNG Images Online?

To compress PNG Images Online, follow these steps.

  • Open the PNG compressor in a browser tab.
  • Upload your PNG files using the upload box. Or you can copy-paste or drag and drop them.
  • The tool will automatically compress your PNG images in a few seconds.
  • If you don’t like the automatic compression result, you can use the slider or enter an exact size to adjust the compression ratio and get another output.
  • Download each PNG image or use the “Download ZIP” button to get them all at once.

You can repeat the process for additional files or use the batch processing feature.

PNG Compressor Key Features 

Our PNG size reducer offers powerful features that make it a strong option for users. Take a look below to see them.

  • Supports bulk uploads. Users can add any number of PNG images as long as their combined size is less than or equal to 50 MB. This enables fast compression of multiple PNG images.
  • Maintains alpha transparency. PNG images are capable of having “Transparent layers.” Ordinary compressors will remove the transparency, but our PNG compressor does not.
  • Minimal loss compression. The lossy algorithm used for compression is very efficient and reduces the amount of data lost.
  • Instant download of compressed PNG image with no login required. No payment either. What’s better than that?
  • No watermark. Typically, free image compressors will put their watermark on the PNG image to advertise themselves. That’s highly inconvenient for users. You will find no such issues in the results of compressed PNG files.

Common Uses of this Compress PNG Tool

This PNG compressor has plenty of uses in the real world. It is commonly used for the following things.

1. Optimize website PNG images for faster loading. A smaller PNG image is faster to load and increases the loading time of a site by a much smaller margin.

2. Reduce file size for better email compatibility. Emails are quite stingy with attachment sizes. Most email providers only let you send an email that is smaller than 10 MB. To make the most of that limited space, you can use the PNG compressor to make your image files smaller so that you can send more of them at once.

3. Compress icons and UI elements for mobile apps. Mobile applications work on a small screen. Just like web pages, they need to be fast, so reducing the size of PNGs in things like icons and blurbs that don’t need to be large is a great practice.

4. Prep PNGs for submission in forms or online applications. Much like emails, many online forms that require links and images have strict file size limits. A PNG compressor can help with meeting those limits.

Frequently Asked Questions (FAQs)

Does this compress PNG tool affect the image’s transparency?

No, this compress PNG tool fully preserves alpha transparency while compressing the file size. So, transparent textures are not affected.

Is the PNG compression lossy or lossless?

The PNG compression is done via an efficient lossy algorithm. This means that data loss by compression is minimal and doesn’t affect the quality.

Can I compress multiple PNG images at once?

Yes, you can compress multiple PNGs at once. You can add as many PNGs as you like, but their combined total size must be 50 MB or less; otherwise, the compression will fail.

Will compressing PNG reduce image resolution?

No, our PNG compression algorithm focuses on removing unnecessary details that are barely noticeable to the eye, such as colors hidden behind opaque layers. The resolution of the final image remains the same.

Does PNG compression affect text or logos in images?

Yes, it does, but not to the point that they can’t be recognized or read. That only happens if you compress an already compressed image, as that results in loss of details. So long as you are not doing that, there will be no loss in detail of text and logos.

Is there a daily limit on PNG compression?

No, you can use it as much as you like. The only limit is that you can’t batch process more than 50 MB of images at once.
