Frequently Asked Questions
What happens when the new size has a different shape?
You choose. Fit keeps the whole image and fills the rest with white, black or (for PNG, WebP and AVIF) transparency. Cover fills the whole size and crops what overflows: drag the image in the frame, or use the Crop position slider, to choose what is kept. Stretch fills the size exactly and changes the image's proportions.
Can I see the result before I download?
Yes. The new size is shown at its real proportions with your image placed in it exactly as it will be saved, at Fit, 100% or 200%. After resizing, the resized file itself is shown, with its pixel size, format and file size.
Can I resize by percentage?
Yes. Choose Percentage and enter 1 to 400%. The image keeps its proportions; in a batch each image is scaled by its own size.
Are there social media size presets?
Yes: Instagram (Post, Story, Landscape), Twitter/X (Post, Header), LinkedIn (Banner, Post), YouTube Thumbnail and Facebook Cover. A preset sets the width and height; choose Fit or Cover for how your image goes in.
Can I save my own sizes?
Yes. Save the current width and height as a preset to use again later. Presets are kept in this browser's storage.
What format is the resized image?
The format of your image: JPEG, PNG, WebP and AVIF stay as they are; GIF and BMP are saved as PNG, and HEIC (iPhone photos) as JPEG. JPEG, WebP and AVIF are saved at quality 92. A GIF is resized as a still image (its first frame).
Does it keep EXIF data?
No. The image is rebuilt from its pixels, so EXIF and other metadata (camera, location, date) are not copied. A photo the camera stored sideways is turned the way it is shown first, so it stays upright.
What happens if I resize larger than the original?
You can, up to 10,000 px on a side. A note warns that enlarging cannot add detail, so the result looks softer.
Can I resize several images at once?
Yes. Add several images: with Width and height they all get the same size and fit, with Percentage each is scaled by its own size. Download them as separate files with one click, or as one ZIP.
