Ready to Reduce PNG File Size?
Add PNG files below.
- Reduce File Size
- Makes files smaller in KB or MB while keeping dimensions unchanged by default. For example, 2 MB → 500 KB when the target is achievable.
- Resize Dimensions
- Changes width and height in pixels. For example, 3023 × 4031 → 1512 × 2016 at 50%.

Losslessly optimize PNG files while preserving supported transparency.
Key Characteristics
Transparency Preserved
Keep supported transparent and partially transparent pixels.
Graphics Friendly
Useful for logos, screenshots and interface assets.
About This Operation
What to Expect
PNG compression is lossless in this tool, making it suitable for logos, screenshots, interface assets and graphics where exact visual detail matters.
Transparency is preserved when present. Because PNG may already be optimized, reductions are often modest and some files will not produce a smaller copy.
Supported input
Accepts validated still PNG files, including PNGs with supported transparency.
Output
Produces losslessly optimized PNG output with transparency and dimensions preserved unless resized.
Simple Workflow
How It Works
- Step 1
Upload Your PNGs
Choose one or more still PNG graphics.
- Step 2
Choose an Optimization Level
Select Light, Balanced or Maximum lossless optimization, and leave resize off to retain dimensions.
- Step 3
Optimize & Download
Optimize, review each measured reduction, then download or share the smaller PNG when one is produced.

Important limitations
- Reductions may be modest
- Already-optimized PNGs may not shrink
- Animated PNG is not supported
Quality Behavior
Current PNG compression is lossless; the three levels change optimization effort, not visible image detail.
Transparency
Transparency behavior follows the selected source and output formats.
Animation and Interactivity
Animated image editing is not supported; still-image validation remains authoritative.
Metadata and Orientation
Embedded metadata is removed by default while supported pixel transparency remains intact.
Built Around Your Files and Privacy
Your Files, Handled with Care
Checked Before Processing
Convert It checks uploaded files against the expected format before processing so invalid or unsupported files can be stopped early.
Your Files Stay Yours
You keep your rights to the files you upload and the converted files you create. Only upload content you have permission to use.
Private, Temporary Processing
Source files are handled in private temporary storage, while converted files follow the retention period for your visitor or account level.
