Frequently asked questions

Is this image resizer really free?+
Yes - completely free, with no signup, no watermark, and no upload limits. We may show ads to keep the tool free, but the core functionality is unrestricted.
Are my images uploaded to a server?+
No. All image processing happens directly in your browser using HTML5 Canvas. Your image never leaves your device. This makes the tool faster and far more private than competitors.
Which platforms are supported?+
Google Business, Facebook, Instagram, LinkedIn, X (Twitter), YouTube, TikTok, Pinterest, and WhatsApp. We generate every required size for each platform from a single upload.
What image formats can I upload?+
JPG, PNG, and WebP files up to roughly 20 MB. Output is PNG by default for maximum quality, or WebP for smaller file sizes — switchable in the Adjust panel.
Can I add custom dimensions?+
Yes. Use the "Custom size" button in Step 1 to add any width × height between 16×16 and 5000×5000 pixels. You can add custom sizes before or after uploading.
