FAQ
Does resizing affect image quality?
Downscaling with high-quality resampling keeps edges clean. For JPG/WebP, ~0.85 quality is a great size/quality tradeoff.
How do I keep the aspect ratio?
Keep “Keep ratio” enabled. Enter width or use the scale slider — height will adjust automatically.
Are images uploaded anywhere?
No. Everything runs locally in your browser.
Which export formats are supported?
PNG, JPG and WebP. PNG ignores quality (lossless); JPG/WebP use the quality parameter.
What sizes are good for the web?
Typically 1280–1920 px width for content, 400–1200 px for thumbnails. JPG/WebP quality 0.8–0.9 is a solid starting point.
