FAQ

How do I merge PDF files online for free?

Open Merge PDF, upload two or more PDFs, drag to reorder, optionally insert blank pages between files, then click Merge PDF. The combined file downloads instantly.

How do I split a PDF into separate pages or ranges?

Choose Split PDF, upload one file, pick Extract Page Range, Split Every Page, Split by Size, selected pages, every N pages, or bookmarks, then download a PDF or ZIP.

Can I rotate only some pages?

Yes. Select “Rotate specific pages”, click pages in the preview or enter a range like 1-3, 7, then choose 90° clockwise, counter-clockwise, or 180°.

Is my PDF private?

Uploads are processed for your request and are not kept as a public library. Avoid uploading highly confidential documents to any online service if that is a concern.

What file size is supported?

Each PDF can be up to 100MB. For merge, add multiple files within that limit; total output size depends on how many pages you combine.

Will quality drop when I merge, split, or rotate?

No. Operations keep original PDF page content. We do not convert pages to low-resolution images for these tools.

Can I reorder PDFs before merging?

Yes. Drag the file cards in the merge list, or use the Page order setting (manual, upload order, or reverse).

Do I need an account?

No. Merge, split, and rotate work without signing up. Create an account only if you want other Idoworx features later.

What browsers are supported?

Modern Chromium, Firefox, and Safari browsers work best. Thumbnail previews use PDF.js in your browser before the server processes the file.

How is this different from Image to PDF?

PDF Editor edits existing PDFs (merge/split/rotate). Image to PDF builds a new PDF from JPG, PNG, and other images.
