PDF Merge — FAQs
Does merging PDFs preserve searchability and formatting?
Yes. Merging combines pages without rasterizing them, so text remains selectable/searchable and formatting is preserved. Processing runs in your browser; documents stay on your device.
How many PDFs can I merge?
There are no artificial limits. Capacity depends on your device memory and file sizes.
Are there limits on file size or page count?
Limits are primarily determined by device memory and the complexity of pages. Larger inputs may take longer to process.
What about bookmarks or a table of contents?
Bookmarks may need updating because page numbers change. A generated table of contents will not auto-update and may require manual edits.
Can I change the order before merging?
Yes. Reorder the queue with drag-and-drop or controls. The output follows your chosen sequence.

About these formats
What is a PNG (Portable Network Graphics) file? .png
PNG is a lossless image format that supports transparency (alpha). It preserves crisp edges and exact pixels, making it ideal for UI graphics, logos, and screenshots.
Best for: graphics with text, sharp lines, transparency. Trade‑off: larger than JPEG/WebP for photos.
MIME: image/png
What is a JPG (Joint Photographic Experts Group) file? .jpg,.jpeg
JPEG is a lossy format optimized for photographs. It achieves small file sizes by discarding fine detail that is hard to perceive.
- Best for: photos.
- Limitations: no transparency; re‑saving repeatedly can introduce artifacts.
MIME: image/jpeg
What is a WebP (Web Picture) file? .webp
WebP is a modern image format offering both lossy and lossless compression, usually producing smaller files than JPEG and PNG at similar quality.
Best for: the web when you want smaller images. Notes: older tools may lack WebP editing/export support.
MIME: image/webp
