Default Quality Settings
The default image quality is set to 100, with a quality range from 1 (lowest) to 100 (highest). Lowering the quality setting can significantly reduce file size while maintaining acceptable visual fidelity.
Image Format and Quality Comparison
The table below illustrates the file sizes of screenshots at different quality settings and formats, based on an 800x600 viewport.
| Quality | PNG Size | JPEG Size |
|---|---|---|
| 100 | 560 KB | 307 KB |
| 80 | 146 KB | 76 KB |
| 60 | 123 KB | 45 KB |
| 40 | 101 KB | 38 KB |
Note that image size will vary depending on website content and viewport dimensions.
We recommend using a quality setting of 80 for a balanced reduction in file size (approximately 4x smaller) while maintaining good overall image quality. This setting strikes a practical balance between performance and visual fidelity, reducing network traffic and storage costs. Still deciding which output format to use? See the PNG vs JPEG format guide for choosing between PNG, JPEG, WEBP, AVIF, and GIF.

Frequently asked questions
How do I control screenshot quality?
Add &quality=VALUE (1-100) to your Add Screenshots request. Lower values reduce file size while higher values preserve fidelity.
Which formats support compression?
PNG and JPEG support quality adjustments. Combine this with WEBP or AVIF outputs for additional savings.
Can I automate optimized image delivery?
Yes. Send optimized screenshots directly to AWS S3, Azure, Google Cloud, Cloudflare R2, or email using request templates, schedules, and webhooks.
