Compress PNG Online

PNG Compressor is an online tool that shrinks PNG file sizes without making your images look worse. It uses smart compression to make images load faster on websites, take up less storage space, and work better across all devices.

PNG compression primarily uses the DEFLATE algorithm, which combines two powerful techniques:

• LZ77 compression: Identifies and replaces repeated data patterns within the image
• Huffman coding: Efficiently encodes data by assigning shorter codes to more frequently occurring patterns

Our PNG compressor builds on this algorithm with extra tricks — like trimming the color palette, removing hidden metadata, and reorganizing the image data — to get even better compression while keeping your image looking the same.

PNG compression usually takes just a few seconds:

• Most images finish compressing within seconds of uploading
• Larger images or higher compression levels may take a bit longer
• You can process multiple images back to back without waiting

It's fast and won't keep you waiting around.

Our PNG Compressor works in a few simple steps:

• Upload: Select your PNG image (maximum 10MB)
• Customize: Pick a compression level — Low, Medium, High, or Maximum
• Process: The tool compresses your image while keeping it looking sharp
• Download: Save your optimized PNG with a much smaller file size

It's quick and simple — no technical know-how needed.

Our PNG Compressor gives you 4 compression levels to choose from:

• Low: Light compression with the best quality — perfect when you just need a small size reduction.
• Medium: A balanced option that shrinks file size noticeably while keeping images looking great.
• High: Strong compression for a much smaller file — ideal for websites and sharing online.
• Maximum: The smallest file size possible — great when you need to save space or bandwidth.

No matter which level you pick, your image stays lossless — every pixel is kept exactly as in the original. The level you pick stays selected as you process images one after another, and you can also download an optional WebP version of the same image.

Our PNG Compressor handles a wide range of image sizes:

• Maximum file size: 10MB per image
• Resolution: All common sizes — from tiny icons to large graphics
• Color types: RGB, RGBA (with transparency), and grayscale

For best results, try resizing very large images before compressing them.

Our PNG Compressor works great for:

• Website and blog images — helps pages load faster
• Social media posts and graphics
• App icons and assets
• Email images and newsletters
• Any project where you need smaller PNG files

Smaller images mean faster loading, less data usage, and a smoother experience for your visitors.

No, compressing with PNG Compressor won't hurt your image quality. We use lossless compression, which means:

• Every pixel stays the same: Your compressed image is pixel-for-pixel identical to the original
• Transparency is kept: Transparent backgrounds and alpha channels stay intact
• Colors don't change: All color values remain exactly as they were
• Fine details are safe: Thin lines, text, and small elements won't get blurry or lost
• No weird artifacts: No blocky spots, fuzziness, or quality loss of any kind

You can compress with confidence — you'll get a much smaller file without giving up any visual quality.

How much you can shrink a file depends on the image content, its original size, and the compression level you pick. Here's what you can usually expect:

• General images: 40-70% smaller across most compression levels
• Simple graphics (logos, icons, text): Up to 95% smaller on very simple graphics, occasionally even more, especially at Maximum compression
• Photos saved as PNG: 30-60% smaller, depending on how detailed and colorful they are
• Images with transparency: 50-80% smaller

After compressing, the tool shows you the exact reduction percentage and both file sizes so you can see the results for yourself.

Here are a few tips to get the most out of our PNG Compressor:

• Start with good quality images: The better your source image, the better your compressed result will look.
• Pick the right level: Medium or High works well for most situations — you get a nice size reduction without visible quality loss.
• PNG is best for certain content: PNG really shines with graphics that have text, sharp edges, logos, or transparent backgrounds.
• Resize first, then compress: If your image is larger than you need, resize it to the target size before compressing.
• Be consistent: When compressing several similar images one after another, keep the same level selected for a uniform look.
• Try different levels: Experiment with all 4 levels to find what works best for your project.

Follow these tips and you'll get the smallest files possible while keeping your images looking sharp.

Downloading your compressed images is easy:

• Once compression finishes, a download button shows up
• Click the 'Download' button to save the compressed image
• The file goes to your browser's default download folder
• You can also right-click and pick 'Save As' to choose a specific folder

No extra software needed — just your browser.

Yes! PNG Compressor doesn't claim any rights to your images. Your compressed files keep their original copyright status, so:

• You can use them on business websites and in marketing
• They're fine for social media, ads, and promotional stuff
• Great for apps, digital products, and online stores
• OK for any commercial use as long as you own the rights to the original images

Just make sure you have the right to use the original images — our tool only compresses them, it doesn't change who owns them.

The uploader accepts these image formats:

• PNG files (.png), including RGB and RGBA images with transparent backgrounds
• JPG / JPEG photos
• GIF and WebP images
• Grayscale and color PNGs

You can download the result as a compressed PNG, and an optional WebP version is offered alongside every compression.

Yes — it's completely free, with no account, no sign-up, and no limit on how many images you compress:

• Unlimited compressions with all 4 levels (Low through Maximum)
• Accepts PNG, JPG, JPEG, GIF, and WebP, with an optional WebP download for every image
• The only limits are per file: a 10MB maximum size, and one image is processed per run — just start the next one straight after
• A clean, ad-free experience

Here's what makes PNG Compressor a great choice:

• Great compression: Big file size reduction while keeping your images looking sharp
• Easy to use: Simple interface — upload, pick a level, and you're done
• 4 compression levels: Choose from Low, Medium, High, or Maximum to get the result you want
• Lossless quality: Your images keep all their original details, colors, and transparency
• Fast processing: Most images finish in seconds, even at Maximum compression
• Format support: Works with standard PNGs, RGBA with transparency, and grayscale — plus JPG, GIF, and WebP input
• Free to use: No account or sign-up, with unlimited compressions

PNG Compressor has a few things going for it compared to tools like TinyPNG:

• More control: 4 adjustable compression levels instead of limited presets
• Fast: Images typically process quickly
• Good format support: Handles complex transparency well and accepts JPG, GIF, and WebP input too
• Free to use: No account or sign-up needed, with unlimited compressions
• Lossless quality: Your images keep every pixel intact

TinyPNG is a good tool too, but many users value the extra control of 4 selectable compression levels.

Yes. The uploader accepts JPG and JPEG photos (as well as GIF and WebP) in addition to PNG, and every image can be downloaded as a compressed PNG or an optional WebP. PNG compression is still where the tool does its best work, especially for:

• Images with transparency
• Graphics with text, logos, and sharp edges
• Fine details and colors that need to stay accurate

Our PNG Compressor is for reducing file size, not changing image resolution. If you need to resize your image, try doing that first with an image editor like Photoshop or GIMP, then compress the resized version with our tool.

When you resize images, especially making them bigger, you can lose quality. Here are a few tips to keep it looking good:
- Start with the highest quality original you have
- Use a good image editor with decent resampling (Photoshop, GIMP, etc.)
- Try not to resize the same image over and over
- If possible, use vector graphics — they scale without losing quality
Our PNG Compressor doesn't resize images right now, but we're working on a resizer tool.
