About PDF Modifier
Free, fast, and private PDF and image tools for everyone
Our Mission
PDF Modifier was created with one clear goal in mind: give people a reliable, free, and private way to work with PDF files and images online. We believe that basic document tools should not cost money, require account creation, or put your personal data at risk. Too many websites lock simple tasks like merging two PDFs or converting an image behind paywalls, subscription forms, or endless upsells. We wanted to build something different. Every tool on our site is free to use, works directly in your browser, and requires zero registration. Whether you are a student assembling an assignment, an employee preparing a report, or someone who just needs to compress a photo before sending it over email, we want PDF Modifier to be the tool you reach for first.
Who We Are
PDF Modifier is operated by Stralen Digital LLC, a small but dedicated team of developers and designers based in the United States. We started this project because we experienced the same frustrations that millions of people face every day: websites that promise free tools but deliver slow performance, confusing interfaces, or hidden charges. Our team combines experience in web development, document processing, and user experience design to build tools that actually work the way you expect them to.
We are not a massive corporation with a bloated product team. We are a lean operation that ships fast, listens to feedback, and prioritizes the features that matter most to our users. If you ever need to reach us, you can send an email to Contact@stralendigital.com and a real person will respond. We read every message and take every suggestion seriously because our users are the reason this site exists.
What We Offer
PDF Modifier is home to over 50 free PDF and image tools, all organized into clear categories so you can find exactly what you need in seconds. Our toolset covers virtually every common document task:
- Organize: Merge multiple PDFs into a single file, split a large document into smaller parts, delete or extract specific pages, reorder pages by dragging and dropping, and rotate pages that were scanned sideways.
- Convert: Turn PDFs into Word documents, Excel spreadsheets, PowerPoint presentations, or images. Convert images and other document formats into PDF. All conversions preserve the original formatting as closely as possible.
- Edit: Add text, images, watermarks, page numbers, and annotations to your PDF files. Sign documents electronically without printing anything out.
- Compress: Reduce the file size of PDFs and images so they are easier to share via email or upload to websites with strict size limits.
- Security: Password protect sensitive documents, remove passwords from files you no longer need to keep locked, redact confidential information, and repair damaged PDFs.
- Image Tools: Compress images, resize them to specific dimensions, crop, rotate, and convert between formats like JPG, PNG, WebP, and GIF.
Each tool supports a wide range of input formats including PDF, DOC, DOCX, XLS, XLSX, PPT, PPTX, TXT, RTF, ODT, EPUB, JPG, JPEG, PNG, GIF, WebP, BMP, TIFF, SVG, HTML, CSV, and Markdown. There is no need to install any software. Everything runs in your web browser, which means you can use PDF Modifier on a Windows PC, a Mac, a Chromebook, an iPad, or an Android phone with the same experience.
