How to compress PNG images

  1. Drop your PNG images into the box above — up to 10 at a time on the free plan.
  2. Choose the number of colors (smart lossy compression, like TinyPNG) or lossless optimization.
  3. Compare the before and after sizes, then download the files or a ZIP.

Why GlideConvert?

  • Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
  • Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
  • Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.

Frequently asked questions

How much smaller will my images get?

Reducing a PNG to 256 well-chosen colors typically cuts 50–80% with no visible difference for screenshots, logos and graphics. Lossless mode saves less (5–20%) but keeps every pixel.

Does compression remove the photo’s metadata?

By default the date taken and camera details are kept in JPG files and the GPS location is removed. You can keep or remove everything in the options.

Can I compress an image to an exact size?

Yes — type a target such as 100 KB and we find the highest quality that fits. Popular targets: 20 KB, 50 KB, 100 KB, 200 KB, 500 KB and 1 MB.

Will the image dimensions change?

No, unless you ask for it. If a target size cannot be reached at a reasonable quality, the image is scaled down a little and you will see the new dimensions.

Which format gives the smallest files?

AVIF and WebP are typically 25–50% smaller than JPG at the same quality — choose them in the format menu if the place you upload to accepts them.

Are my files uploaded to a server?

No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
