Why PNG images are different from JPG photos
PNG is commonly used for screenshots, logos, icons, UI graphics, transparent images and images with sharp edges. Unlike JPG, which is mostly used for camera photos, PNG is often chosen when text, lines, icons or transparent backgrounds need to stay clean.
This is why PNG files can stay large after compression. A screenshot with small text, buttons, menus and interface details can contain a lot of sharp information. A transparent logo may also need extra data to keep edges smooth. This PNG compressor is built to reduce file size while still helping you keep the image useful for upload, documents, websites and sharing.
When PNG is the right format
PNG is not always the smallest format, but it is often the right choice when image clarity matters more than the smallest possible file size. Before converting your PNG to another format, check whether the image needs transparency, sharp text or clean graphic edges.
Best for
Screenshots, logos, icons, UI graphics, diagrams, transparent images and images with sharp text.
Not ideal for
Large camera photos, portraits, product photography and natural images where JPG usually compresses better.
Try WebP if
You want smaller website images and your workflow supports WebP, especially for modern web performance.
Best settings for PNG compression
PNG compression works best when the image does not contain unnecessary pixels. If the PNG is a large screenshot, reducing the maximum width can help. If it is a logo or icon, cropping empty space around the artwork can reduce file size without hurting the important part.
Screenshot
Resize large screenshots carefully and check that small text is still readable after compression.
Logo
Crop extra transparent space and keep enough resolution for clean edges on different screens.
Document image
Use PNG when text clarity matters, but avoid extreme target sizes that make letters hard to read.
Website graphic
For modern websites, compare compressed PNG with WebP if you want a smaller file.
PNG is useful, but not always the smallest
If your PNG file is still too large after compression, it may be because the image contains transparency, sharp text, complex graphics or too many pixels. In that case, you can resize the PNG, compress it to a target KB size or convert it to another format when transparency is not required.
PNG compression problems and fixes
The PNG is still too large
The image may contain transparency, high resolution or detailed graphics. Try reducing maximum width or converting to WebP if transparency support is acceptable.
Small text becomes hard to read
Do not resize text-heavy screenshots too aggressively. Use a larger target size if readability matters.
Transparent edges look different
Preview the image before using it. Transparent logos and icons need enough quality and resolution to keep smooth edges.
The upload form rejects the PNG
Some portals require a specific file size, dimensions or format. Check whether the form accepts PNG or asks for JPG instead.
PNG vs JPG vs WebP
The best format depends on the image. PNG is strong for sharp graphics and transparency. JPG is usually better for photos. WebP is useful for modern websites because it can often reduce file size while keeping good visual quality.
Tips before downloading your compressed PNG
FAQs
Questions about this image tool
Why is my PNG file so large?
PNG files can be large because they are often used for sharp screenshots, graphics, transparency and images with clean edges. These details can take more file space than a normal JPG photo.
Can PNG compression keep transparency?
PNG supports transparency, but the final behavior depends on the compression method and output format. If transparency is important, preview the compressed image before using it.
Is PNG good for screenshots?
Yes. PNG is often good for screenshots because it keeps text, icons and interface edges sharp. However, screenshots can still become large, especially at high resolution.
Can I compress PNG to 100KB?
Yes, you can enter 100KB as a target size. Very detailed PNG files or large screenshots may also need resizing to reach 100KB.
Should I convert PNG to JPG or WebP?
If transparency is not needed, JPG or WebP may create a smaller file. If transparency, sharp icons or clean text are important, PNG may still be the better choice.
