Compress Screenshots Online — Preserve Text Clarity
Optimize screenshots for sharing and documentation
For screenshots with UI text, thin lines, or flat color blocks, start with PNG to preserve visual edges. If file size matters more, test WebP first and compare text clarity at the same dimensions. If text becomes soft, raise quality or switch back to PNG rather than applying more JPEG compression.

Screenshot Compression Tips
Optimize for your use case
Different scenarios require different compression strategies. Our presets are tailored specifically for screenshots.
Use the right format
Modern formats like WebP and AVIF can provide significant file size savings compared to traditional formats.
Batch process similar images
Save time by processing multiple images with the same settings using our batch compression feature.
Preview before saving
Always check the compressed result to ensure it meets your quality standards before downloading.
Best format for this task
Why PNG works well
- • logos
- • UI assets
- • screenshots
- • graphics with text and flat colors
Alternatives to consider
- • WEBP: lossy mode for photos with transparency, far smaller
- • JPEG: much smaller for photos when transparency is not needed
Real-world compression test results
Encoded with the codecs this tool ships, on a synthetic ui-screenshot source. Sizes are actual output bytes, not estimates.
| Source | Dimensions | Input | Output | Size | Saved | Observed tradeoff |
|---|---|---|---|---|---|---|
| UI screenshot | 1280×800 | 142 KB | JPEG q70 | 25 KB | 82.1% | visible softening on fine edges and text; gradients stay smooth |
| UI screenshot | 1280×800 | 142 KB | JPEG q85 | 33 KB | 76.8% | minor edge softening; flat color areas remain clean |
| UI screenshot | 1280×800 | 142 KB | WEBP q70 | 5 KB | 96.8% | slight blur in gradients; edges hold up better than JPEG; alpha preserved |
| UI screenshot | 1280×800 | 142 KB | WEBP q85 | 5 KB | 96.2% | near-original quality; alpha preserved |
| UI screenshot | 1280×800 | 142 KB | AVIF q70 | 1 KB | 99.2% | compression artifacts visible only in fine gradients; alpha preserved; encode is slowest |
| UI screenshot | 1280×800 | 142 KB | AVIF q85 | 1 KB | 99.1% | excellent quality at small size; alpha preserved; encode is slowest |
