Pertanyaan yang sering ditanyakan
Will resizing lose quality?
Downscaling is lossless in perception - the resizer uses high-quality bilinear resampling. Upscaling always loses sharpness; for that, an AI upscaler is a better tool.
Does the output format match the input?
By default yes. Optionally export a resized PNG as JPG or WebP for smaller file size.
What are the social presets?
Instagram square (1080×1080), Instagram story (1080×1920), YouTube thumbnail (1280×720), Twitter/X post (1600×900), LinkedIn banner (1584×396), and Facebook cover (820×312).
Are my images uploaded?
No. Resizing runs in your browser via the Canvas API.
