Why use Change Aspect Ratio on 108pdf
Change Aspect Ratio runs entirely in your browser. Your file is opened by your own device, processed there and saved back to you, so it is never uploaded to a server and never stored by us. That makes it safe for ID cards, exam forms, contracts and any other document you would rather keep private.
There is no account to create, no watermark on the result and no daily limit. You can process as many files as you like, one after another, and the tool keeps working even on a slow connection once the page has loaded.
If the result is not what you expected, change the options and run Change Aspect Ratio again on the same file. Nothing is lost, and your original file is never touched. Use the related tools below to continue the job, for example to resize, convert or merge the output.
