Frequently Asked Questions
Is there a limit to how many PDF files I can merge?▼
We don't cap the number of files. Since everything runs locally in your browser, you can usually combine dozens of PDFs at once — the real limit is just how much memory your phone or computer has free.
Will merging reduce the quality of my original PDFs?▼
Ні. Об’єднання лише зшиває наявні сторінки впритул; він не стискає повторно зображення чи повторно відтворює текст, тому шрифти, фотографії та форматування виходять точно такими, якими вони були.
Is it safe to merge sensitive or confidential documents here?▼
Yes. Your files are combined inside your own browser tab and never uploaded to a server, so contracts, IDs, or financial statements never leave your device.
Чи можна об’єднати PDF-файли різних розмірів, наприклад A4 і Letter?▼
Yes — use the page size option to force every page to A4 or US Letter, or leave it on "Original" to keep each file's own dimensions untouched.
Що робити, якщо один із моїх PDF-файлів захищено паролем?▼
You'll need to remove the password first. If we detect an encrypted file during merging, we'll point you to the Unlock PDF tool so you can strip the password before combining.
