Frequently Asked Questions
Can I resize multiple images at once?
Yes! You can upload multiple images simultaneously and apply the same resize settings to all of them using the "Apply Resize to All Photos" button. This saves significant time when processing many images with the same requirements.
Will resizing affect image quality?
Our resizing algorithm is designed to maintain the best possible quality. When enlarging images, some quality loss is inevitable, but when reducing size, the quality is generally well-preserved. For the best results, avoid enlarging images beyond their original dimensions.
What social media sizes are supported?
We support all major social media dimensions including Instagram Square (1080×1080), Instagram Portrait (1080×1350), Facebook Cover (1200×630), Twitter Header (1500×500), LinkedIn Square (1024×1024), Pinterest Square (1200×1200), and YouTube Thumbnail (1920×1080).
Are my images uploaded to your servers?
No, absolutely not! All image processing happens locally in your browser using JavaScript. Your images never leave your device or get uploaded to our servers, ensuring complete privacy and security of your photos.
Can I resize iPhone HEIC photos?
Yes! Our tool automatically detects and converts HEIC files (iPhone photos) to JPEG format before resizing. You'll see a conversion progress modal during this process, and then you can resize the converted images normally.
What's the maximum file size I can upload?
Since processing happens in your browser, the limit depends on your device's available memory. Most modern devices can handle images up to 50-100MB without issues. Very large files may take longer to process or cause performance issues on older devices.
How do I maintain aspect ratio when resizing?
When using the "Size" method, make sure the "Maintain aspect ratio" checkbox is checked. This will automatically adjust the height when you change the width (or vice versa) to keep the image proportions intact and prevent distortion.
Can I resize animated GIFs?
Yes, you can resize GIF files, but note that the animation will be converted to a static image. If you need to maintain animation, we recommend using specialized GIF editing tools that preserve frame sequences.
