Frequently Asked Questions
What image formats can I resize?
Our image resizer supports all popular formats including JPG, JPEG, PNG, WEBP, BMP, TIFF, and GIF. You can also convert between formats during the resize process. For example, resize a PNG and save it as JPG, or convert JPG to WEBP for better compression.
Can I resize images for social media platforms?
Absolutely! We provide preset dimensions for all major social media platforms: Instagram posts (1080×1080), Instagram stories (1080×1920), Facebook covers (851×315), YouTube thumbnails (1280×720), Twitter headers (1500×500), LinkedIn posts (1200×627), and Pinterest pins (735×1102).
Does resizing reduce image quality?
Our smart algorithms maintain maximum quality while resizing. When you increase image size, we use advanced interpolation to minimize pixelation. When reducing size, we preserve important details and sharpness. You can control compression quality (0-100%) and choose output formats that best preserve image details.
Can I resize multiple images at once?
Yes! Our batch image resizer allows you to upload and resize multiple images simultaneously with the same settings. This saves significant time when preparing images for websites, social media, or print projects. All images will be processed with identical dimensions, quality, and format settings.
What's the maximum image size I can upload?
You can upload images up to 20MB each, which accommodates high-resolution photos from professional cameras, smartphones, and scanners. This limit ensures fast processing while covering virtually all use cases, from social media posts to high-resolution print materials.
Can I set custom DPI for print images?
Absolutely! Set custom DPI (dots per inch) from 72 for web images to 300+ for high-quality printing. Use 72-96 DPI for web and social media, 150 DPI for basic printing, 300 DPI for professional photo printing, and 600+ DPI for specialized print applications like fine art reproduction.
How do I maintain aspect ratio when resizing?
Toggle the "Maintain Aspect Ratio" switch to automatically calculate proportional dimensions. When enabled, changing the width will automatically adjust the height to maintain the original image proportions, preventing distortion and stretching.
Can I use different units like centimeters and inches?
Yes! Choose from pixels (px) for digital use, percentages (%) for proportional scaling, centimeters (cm) for metric measurements, or inches (in) for imperial measurements. This is especially useful when preparing images for print projects where physical dimensions matter.
What happens to transparent backgrounds when resizing?
When resizing PNG images with transparency, you can choose to preserve the transparent background or replace it with a solid color using our background color picker. This is useful when converting to formats like JPG that don't support transparency.
Is this tool better than Photoshop for resizing?
For simple resizing tasks, our tool offers several advantages: it's completely free, requires no installation, includes social media presets, supports batch processing, and provides instant results. While Photoshop offers more advanced editing features, our tool is perfect for quick, professional resizing without the complexity or cost.
