Frequently Asked Questions

What's the difference between DPI and pixels? expand_more

Pixels (px) are the absolute dimensions of an image on a screen (e.g., 1920x1080 px). DPI (Dots Per Inch) is a print measurement that determines how many pixels are printed in one inch. For web use, you only need to worry about pixel dimensions; DPI is irrelevant for screen display.

How do I maintain the aspect ratio? expand_more

Our tool has a "Maintain aspect ratio" option enabled by default. When you enter a new width, the height is automatically calculated to keep the original proportions, preventing your image from being stretched or distorted. You can uncheck this if you need specific, non-proportional dimensions.

Can I increase the image size (upscale) without losing quality? expand_more

Upscaling an image (making it larger) involves creating new pixels, which can lead to a loss of sharpness and the appearance of artifacts. While our tool uses advanced algorithms to minimize this, upscaling will never have the same quality as the original. It's always best to start with a high-resolution image and downscale it.

What is the best format to use when resizing images? expand_more

For photos, JPG is usually the best choice as it provides good quality at a small file size. For graphics with transparency, text, or sharp lines (like logos and screenshots), PNG is the ideal format because it is lossless and preserves quality perfectly. WebP is a great modern alternative for web use, offering the benefits of both.

What are the ideal dimensions for social media? expand_more

Common dimensions are 1080x1080 px for Instagram posts, 1200x630 px for Facebook link posts, and 1600x900 px for X (Twitter) posts. Our tool includes presets for these and other popular sizes to make resizing for social media quick and easy.
