PNG Compressor
Make PNG files smaller in seconds, and keep them as PNG with transparency.
Drop in your PNG images and shrink them in one go. Compression reduces the number of colours, which makes logos, icons, screenshots and graphics much lighter while transparent backgrounds stay intact. Choose the quality, optionally limit the width, and download the smaller PNGs one by one or as a ZIP. Add up to 50 files at once. Everything runs in your browser, so nothing is uploaded. Free, with no sign-up and no watermark.

Why Compress PNG Files?
To compress a PNG, reduce the number of colours it uses and scale it down if it is wider than it needs to be. Because PNG is lossless, it can't simply "lower the quality" the way JPG does. Teasoft's PNG Compressor does the colour reduction in your browser, keeps transparency, and returns a smaller PNG: add your files, choose the quality (70% suits most graphics), click Compress images and download.
PNG is the right format for logos, icons, screenshots and graphics with transparency, but its files can be surprisingly heavy. A full-screen screenshot or a design export can easily be several megabytes, which slows down web pages, bloats email attachments and runs into upload limits.
PNG is lossless, so it shrinks differently from JPG. There are two main ways to make a PNG smaller, and this tool gives you both:
1. Reduce the number of colours. A graphic with flat colours rarely needs millions of them. Storing it with a limited palette (up to 256 colours at the default setting) can cut the file size dramatically, often with no visible difference for logos, icons, UI screenshots and illustrations.
2. Reduce the dimensions. A 3000 px logo shown at 600 px wide wastes most of its pixels. Limiting the width removes them.
Transparent backgrounds are kept either way, which is the main reason to compress a PNG rather than turn it into a JPG.
Common reasons to compress PNG files:
- A logo, icon or graphic is too heavy for your website and slows the page.
- A form, portal or marketplace rejects PNG files over a size limit.
- Screenshots are too big to email or paste into a document.
- You want to keep transparency, so JPG isn't an option.
- You are running out of storage and have many screenshots or exports.
- You are preparing graphics for a presentation, newsletter or app.
What each setting does:
| Setting | What it does | When to use it |
|---|---|---|
| Quality | Lower values reduce the number of colours and make smaller files. Default is 70% (256 colours). At 95–100% every colour is kept and the file is only recompressed. | 70% suits most graphics. Go higher for gradients, soft shadows and detailed art. |
| Limit width | Scales images wider than your limit down to it. Narrower images are left alone. | Oversized screenshots and exports, or any image bigger than it will be shown. |
Good to know
- Colour reduction changes the image. On flat graphics it is usually invisible. On gradients, soft shadows and photos, you may see banding or a slightly grainy look. Check the result before using it.
- Photos don't compress well as PNG. A photo saved as PNG stays large even after compression. If you don't need transparency, PNG to JPG or PNG to WebP will give a far smaller file.
- Don't compress the same PNG over and over. Each pass at a lower quality removes more colours. Compress once from your original.
- Some PNGs barely shrink. Files that were already optimised, or very small icons, may not change much. Check the size after compressing.
What You Can Do With This Compressor
- Control the quality. The slider starts at 70%. Lower values use fewer colours and make smaller files. At 95–100% every colour is kept.
- Transparency kept. Transparent backgrounds and soft edges stay transparent, so logos and cut-outs still work on any background.
- Limit the width. Set a maximum width in pixels. Wider images are scaled down, narrower ones are left untouched.
- Stays PNG. Your files keep the format that design tools, documents and websites all accept.
- Compress in bulk. Add up to 50 PNGs at once, each up to 100 MB, and download them all as one ZIP.
- Private by design. Files are processed in your browser and never uploaded to a server, which matters for client logos, unreleased designs and screenshots with sensitive content.
- Add files your way. Drag and drop, browse, or paste with Ctrl+V (handy for a fresh screenshot).
- No sign-up, no watermark, no fees.
- Works on any device. Windows, Mac, Linux, Android and iPhone, in any modern browser.
Which Image Tool Should I Use?
Use the PNG Compressor when you have PNG files and want them smaller as PNG, especially if they need transparency. If you don't need transparency, or the image is a photo, a different format will be much smaller. If your files are in another format, use the general Image Compressor.
How to Compress PNG Images (3 Steps)
Add your PNG images
Drag and drop your files, click browse, or press Ctrl+V to paste. You can add up to 50 PNG files, each up to 100 MB.
Choose your settings
Open Settings. Keep quality at 70% for most graphics. Raise it for gradients and detailed art, or lower it for the smallest files. If your images are very large, set a maximum width.
Compress and download
Click Compress images, check the sizes and how the images look, then save each file or use Download to get everything in one ZIP.
Tip: zoom in on the compressed PNG, especially on gradients, shadows and edges, before you replace the original on your site.
Which Settings Should I Use?
| Your image | Quality | Limit width | Notes |
|---|---|---|---|
| Logo or icon with flat colours | 70% (default) | About 2× the size it is shown at | Usually the biggest savings, with no visible change. |
| UI screenshot or screenshot with text | 70–85% | 1280–1920 px | Zoom in and check text edges. |
| Illustration or flat graphic | 70–80% | As needed | Check for banding in large flat areas. |
| Graphic with gradients or soft shadows | 85–95% | As needed | Low quality can cause visible banding. |
| Brand colours or print master that must stay exact | 95–100% | Leave empty | Every colour is kept, so savings are smaller. |
| Photo | Not recommended | n/a | Use PNG to JPG or PNG to WebP instead. |
These are starting points, not guarantees. Check the size and the look of the result, then adjust.
PNG, JPG or WebP: which is right?
| Choose | When |
|---|---|
| Compress PNG (this tool) | You need PNG, with transparency: logos, icons, UI graphics, design handoffs. |
| PNG to WebP | The graphic is for a website and you want the smallest file with transparency. |
| PNG to JPG | No transparency is needed, or it is a photo or a screenshot of a photo. |
How to get a PNG under a size limit (for example 100 KB, 200 KB or 1 MB):
This tool does not target an exact file size, so use this routine: set a maximum width that suits the image (width gives the biggest saving), start at 70% quality, then check the size. If it is still too big, lower the quality in steps of 5–10% or reduce the width, and compress again from your original. If a photo-like PNG won’t get small enough, convert it to JPG or WebP instead.
Tips for compressing PNGs
- Keep the original files until you've checked the compressed versions.
- Compress from the original each time, not from an already compressed copy.
- Check the result on both light and dark backgrounds if the image has transparency.
- Use one setting for the whole batch. If some images need different treatment (for example gradients), compress them separately at a higher quality.
- Have JPG, WebP or other formats? Use the Image Compressor, or convert them to PNG first with Images to PNG.
Frequently Asked Questions
How do I compress a PNG?
Open Teasoft's PNG Compressor, add your images, keep quality at 70% for most graphics, optionally set a maximum width, click Compress images and download the smaller PNGs individually or as a ZIP.
How does PNG compression work?
PNG is lossless, so it doesn't discard detail the way JPG does. To make a PNG much smaller, the tool reduces the number of colours (up to 256 at the default setting) and recompresses the file. For logos, icons, screenshots and flat graphics the difference is usually hard to see.
Does compressing a PNG keep transparency?
Yes. Transparent backgrounds and soft edges are kept, so the compressed PNG still works on any background.
Does compressing a PNG reduce quality?
It can. At lower quality settings the number of colours is reduced, which is invisible on flat graphics but can cause banding on gradients and soft shadows. At 95–100% every colour is kept and the file is only recompressed, so the look doesn't change. Keep your originals either way.
What quality should I use for PNG?
The default is 70% (256 colours), which suits most logos, icons and screenshots. Use 85–95% for gradients, shadows and detailed art, and 95–100% when every colour must stay exact.
Why is my PNG still large after compressing?
Photos and images with lots of colour and fine detail don't compress well as PNG. Try limiting the width, or switch format: PNG to JPG for photos, or PNG to WebP to keep transparency with a much smaller file.
What does the "Limit width" setting do?
It scales down any image wider than the value you enter, in pixels, and keeps the proportions. Images that are already narrower are left as they are. Reducing the width is often the biggest saving for oversized screenshots and exports.
How do I compress a PNG to 100 KB, 200 KB or 500 KB?
The tool doesn't target an exact size, but you can get there in a few tries. Set a smaller maximum width, start at 70% quality and check the file size. Lower the quality a little and compress again from your original until it fits.
Why did my compressed PNG get bigger?
It shouldn't. If the compressed version would be the same size or larger, which can happen when the original was already well optimised, the tool keeps your original file and shows "Already well optimised, original kept". To get a smaller file, try a lower quality or a smaller width.
Should I compress a PNG or convert it to JPG or WebP?
Compress it as PNG if you need PNG, or transparency in a widely supported format. Convert to WebP for a smaller website image that still keeps transparency. Convert to JPG for photos or when transparency isn't needed.
Can I compress JPG, WebP or other formats here?
This tool is for PNG files only. For JPG use Teasoft's JPG Compressor, and for JPG, WebP, GIF, BMP or AVIF with a choice of output format use the Image Compressor.
How many PNGs can I compress at once?
You can add up to 50 files in one batch, each up to 100 MB.
Are my files uploaded to a server?
No. Compression happens in your browser, and your files are never uploaded.
Can I compress PNGs on my phone?
Yes. The tool works in the browser on Android, iPhone, tablets and computers. You do not need to install an app.
Is the PNG Compressor free?
Yes. It is free, with no sign-up, no watermark and no hidden fees.
