Resize Settings Explained
Fill and crop
Best for social platforms because the canvas is completely filled, even if the edges need a small crop.
Fit inside
Best when you must keep the entire image visible. Empty space is filled with your chosen background color.
Popular Social Media Image Sizes
Social platforms crop and preview images differently. A YouTube thumbnail usually works best at 1280 x 720, Instagram square posts at 1080 x 1080, stories and reels at 1080 x 1920, and Pinterest pins at 1000 x 1500. This tool gives you those sizes without forcing you to open a design app.

Does resizing reduce quality?
Resizing changes the pixel dimensions. For JPG and WEBP, use a high quality value when you want sharper output.
Which fit mode should I use?
Use fill and crop for social posts, fit inside for product images where every edge must stay visible, and stretch only when exact distortion is acceptable.
Does this work on mobile?
Yes. The tool is responsive, but large batches are smoother on desktop browsers because image resizing uses device memory.
