Make PNG files smaller so they fit email attachments, upload forms and messaging apps. Choose how strong the compression should be, upload the file and download the result — it never comes back bigger than the original.

Compression levels
- Light
- Removes metadata and recompresses with maximum effort, keeping every colour.
- Balanced
- Reduces the image to 256 colours and at most 2560 px — usually a large saving with little visible change.
- Strong
- 128 colours and at most 1600 px for the smallest file.
Why compress a PNG image?
- Lighter images make websites load faster, which also helps search rankings.
- Many forms and marketplaces limit the size of each photo.
- Smaller photos take less space in your phone, cloud and email.
Tips for compressing PNG image files
- Compress the original, not a copy that was already compressed: each pass loses a little more detail.
- For photos, JPG or WebP is usually much smaller than PNG — consider converting instead.
- Metadata such as camera details and GPS location is removed from the compressed file.
What is PNG?
PNG uses lossless compression and supports full transparency, which makes it ideal for logos, screenshots, icons and graphics with text or sharp edges. For photographs it produces much larger files than JPG.
Frequently asked questions
- Is it free to compress PNG image files?
- Yes. Free accounts can process files up to 50MB, 10 times every 24 hours; Pro raises that to 1.5GB with no daily limit.
- Will the quality drop?
- It depends on the level: light is visually almost identical, strong trades some quality for the smallest file.
- How much smaller will my file get?
- It depends on the content: files with large photos or high-resolution video shrink the most. If a file cannot be made smaller, you get the original back unchanged — never a bigger file.
- Is my file safe?
- Files travel over an encrypted connection, are scanned for malware (files up to 200 MB) and are deleted automatically: after 1 hour without an account, 24 hours with a free account, or 7 days with Pro.
- Can I compress files on my phone?
- Yes. It works in any modern browser on Android, iPhone, tablets and computers.
- Does the compressed file get a watermark?
- No. The PNG you download has no watermark, logo or added page.
- Which compression level should I choose?
- Start with balanced. If the file is still too big, try strong; if you notice quality loss, use light.
