Frequently Asked Questions
What image sizes do social media platforms use?
Each platform has different recommended sizes: Instagram feed (1080×1080), Twitter post (1600×900), LinkedIn (1200×627), Pinterest (1000×1500), and many more variations.
Does resizing affect image quality?
This tool uses Canvas API with quality controls. You can adjust the output quality and choose between PNG (lossless) and JPG (smaller file size) formats.
Is there a file size limit?
The tool processes images entirely in your browser. There's no upload limit, but very large images (50MB+) may be slow to process depending on your device.
