How to Merge PDF Files Online (Free)

Combine multiple PDF documents into one file in seconds — no software install required.

When to use merge PDF

Combine scanned pages, reports, or invoices into a single document for emailing or printing.

Steps

Open the Merge PDF tool from the homepage.

Upload two or more PDF files (order matters — rearrange if needed).

Click Process and wait for the merge to complete.

Download the combined PDF. The original uploads are deleted from our servers within about an hour.

Tips

For best results, use PDFs without password protection. Very large files may take longer on the free tier.

Remove Image Background Online

Create transparent PNGs for product photos, profile pictures, and design projects.

Overview

Our background remover uses AI to detect the subject and remove the backdrop automatically.

Steps

Go to Remove Background in the Image category.

Upload JPG, PNG, or WebP (clear subject works best).

Process the image and download a PNG with transparency.

Best practices

Use good lighting and a contrasting background. Complex hair edges may need touch-up in a photo editor.

Compress Video Without Losing Too Much Quality

Reduce video file size for email, social media, or storage — adjust quality to fit your needs.

Why compress?

Large MP4/MOV files are hard to share. Compression lowers bitrate and resolution to shrink file size.

Steps

Open Compress Video under Video tools.

Upload your video and choose a quality preset (lower = smaller file).

Download the compressed output when ready.

Note

Processing time depends on length and resolution. Pro users get priority queue and higher size limits.
