Common resizing questions
Is it free?
Yes. No account or watermark. Website analytics are on by default and can be turned off in the footer. We do not collect images or filenames.
Does enlarging improve sharpness?
No. Increasing the dimensions cannot restore missing detail. Transparent areas are filled with a background color when exported as JPEG.
Which platforms are supported?
13 presets for Instagram, X, LinkedIn, Facebook, YouTube and TikTok, plus custom sizes. Check how your export displays on the platform before posting.
