Can I merge PDFs without uploading them?
Yes. Hasmar PDF combines PDF pages in your browser. Select two or more PDFs, review their page order and download one merged document. Your document contents are not sent to a processing server.
How do I combine lecture notes in the right order?
Add the PDFs for each lecture, then drag the page thumbnails into the sequence you want. Remove cover pages or duplicates before downloading. Check the first and last page of each section in the result.
Will merging compress my PDF?
This tool copies PDF pages rather than rasterizing them. It is not a PDF compressor. Forms, bookmarks, annotations and digital signatures may not survive editing; keep your originals.

Which PDFs can I use?
Use standard, unencrypted PDFs. Password-protected or damaged files aren't supported. Editing digitally signed PDFs can invalidate signatures; interactive forms, bookmarks and annotations may not survive page copying. Keep the original for these documents. Large scans may exceed your device's available memory even below the file-size limit.
Are my documents uploaded?
No. PDF and photo processing happens in your browser. The tool does not send your file contents to a processing server.
Is Hasmar PDF free to use?
Yes. These tools have no subscription, per-file fee or added watermark. File-size and page limits help protect your device's memory.
Can I arrange photos before converting?
Yes. Open Photo to PDF, add JPG, PNG or WebP images, then drag them into order or use the arrows. Each photo becomes one page.
