Frequently Asked Questions
Downscaling (making an image smaller) generally retains high visual quality if using a good resampler like Bicubic. Upscaling (making it larger) will eventually lead to pixelation as the computer has to "guess" new pixel data.
Aspect Ratio is the proportional relationship between width and height. Locking it ensures that when you change the width, the height changes accordingly, preventing the image from looking "stretched" or unnatural.
Our engine is optimized for high-fidelity single and small-batch processing. For thousands of images, we recommend professional desktop software, but for web-ready assets, our browser tool is unbeatable for speed.
WebP and AVIF are the standards for web performance. They offer 30% better compression than JPEG at the same quality level, helping your Core Web Vitals scores.
Dimensions are only half the battle. After resizing, you may need a second pass with an image compressor to reduce the metadata and optimize the bit-depth of the pixels.
Yes. Our canvas-based engine preserves Alpha transparency, ensuring your logos and icons remain transparent after the resize operation.
The current requirement is 1280 x 720 pixels with a minimum width of 640 pixels. Always keep the file under 2MB for upload compatibility.
DPI (Dots Per Inch) is mostly relevant for print. For digital web use, the only measurement that truly matters is the absolute pixel width and height (e.g. 1920x1080).
This requires variable quality compression. You can resize to smaller dimensions first, then adjust the quality slider in your export settings until the target file size is reached.
