Its difference is where files go. Twenty everyday tools β merge, split, organize, compress, edit, sign, watermark, protect, unlock, image tools and more β run entirely inside your browser, so those files are never uploaded. OCR, Office conversion and AI run on a secure server, and those files are deleted within one hour.

Smallpdf vs PDFTrusted: Essential PDF Tools
Smallpdf has a few more specialist tools; PDFTrusted matches the core jobs and runs most of them on your device.
PDFTrustedMost people use a handful of tools again and again: merge, compress, convert to and from Word, and sign. We looked at how each product handles those jobs, and what extra tools are there when you need them.
Merging and organizing PDFs: both are easy; PDFTrusted keeps the files on your device
Smallpdf: Smallpdfβs merger is a browser-based combiner with no installation: drop your files, arrange them and combine. Files are encrypted with TLS and removed from its servers after one hour.
PDFTrusted: PDFTrusted merges PDFs and photos (JPG, PNG, HEIC and more) into one file, with page reordering and blank-page insertion. The whole job runs inside your browser, so the files never leave your device. Split, extract, delete, rotate and organize work the same way.
Compressing PDFs: Smallpdf reserves its strongest level for Pro; PDFTrusted compresses on your device for free
Smallpdf: Smallpdf says it can reduce PDF size by up to 99%. Basic compression is free; Strong Compression is a Pro feature. Like merge, files are deleted from its servers after one hour.
PDFTrusted: PDFTrusted compresses in your browser and shows the size before and after. You choose Extreme, Recommended or Less, which helps with strict upload limits like 100 KB or 200 KB. Free files can be up to 25 MB.
Converting to and from Office: both convert both ways; Smallpdf adds OCR conversion on Pro
Smallpdf: Smallpdf converts to and from Word, Excel, PowerPoint and images, and also handles HWP, Pages, EPUB, ZIP and CSV to PDF. OCR inside PDF to Word, Excel and PPT is a Pro feature.
PDFTrusted: PDFTrusted converts PDF to Word, Excel and PowerPoint and back, plus OpenOffice files, RTF, HTML, web pages (URL), EPUB, TXT, CSV and ZIP to PDF. Office conversions run on a secure server and the files are deleted within one hour. Free conversions handle up to 20 pages.
Signing and specialist tools: Smallpdf adds signature requests and redaction; PDFTrusted signs privately on your device
Smallpdf: Smallpdf signs documents and, through the Sign.com Premium subscription included in Pro, sends signature requests with templates and an activity timeline. It also has redaction, crop, flatten, a form filler and an annotator.
PDFTrusted: PDFTrustedβs Sign PDF lets you draw, type or upload your signature and place it on any page, all inside your browser. It also edits text, adds watermarks and page numbers, protects and unlocks PDFs, and repairs damaged files. Signature requests, redaction and compare are not available yet.
Verdict: Smallpdf has more specialist tools, including redaction, a form filler and signature requests. For the everyday set β merge, compress, convert, sign, protect β both do the job well, and PDFTrusted keeps most of those files on your device.
Smallpdf vs PDFTrusted: Ease of Use
Both are easy: one tool per page, one upload button, one download.
PDFTrustedOnline PDF tools win or lose on the first minute. We looked at how quickly a new visitor can find the tool, understand the options and download a result β on desktop and on a phone.
Interface and first-time experience: a tie β both get you from upload to download in a few clicks
Smallpdf: Smallpdf leads with βWe make PDF easy.β and keeps that promise: spacious pages, a big drop zone, and a short plain-language explanation of each tool right below it.
PDFTrusted: PDFTrusted uses one job per screen with plain options, large tap targets and a result card showing what changed (for example, the size saved). The same layout works on phones, so finishing a form upload from a mobile browser is as easy as on a laptop.
Languages and help: Smallpdf offers more languages; PDFTrusted localizes each tool page in 18
Smallpdf: Smallpdfβs language menu lists 24 languages, with a help center, a blog full of how-to guides, and priority support on paid plans.
PDFTrusted: PDFTrusted is available in 18 languages, each with native, translated tool pages and URLs. Every tool page includes a step-by-step guide and FAQ, and support is by email (priority on Pro).
Verdict: Both are easy. Smallpdf is very guided with a friendly design; PDFTrusted is built phone-first and shows a clear result after every job.
Smallpdf vs PDFTrusted: Privacy and Security
Smallpdf is ISO/IEC 27001 certified and deletes uploads after 1 hour; PDFTrusted avoids uploading everyday files at all.
PDFTrustedBank statements, IDs, contracts and medical letters all pass through PDF tools. Security has two parts: how well a provider protects files on its servers, and whether the files need to reach a server in the first place.
Where your files are processed: PDFTrusted processes everyday tools on your device; Smallpdf uses its servers
Smallpdf: Files are uploaded over 256-bit TLS and processed on Smallpdfβs servers. Its tools are browser-based in the sense that nothing needs installing, but the processing happens server-side.
PDFTrusted: Twenty everyday tools β merge, split, organize, rotate, compress, edit, sign, watermark, page numbers, protect, unlock, repair and image conversions β run inside your browser using your device. For those jobs the file is never uploaded. OCR, Office conversion and AI need a server and are sent over HTTPS.
Retention, encryption and certifications: Smallpdf has formal certification; both delete server files within an hour
Smallpdf: Smallpdf is ISO/IEC 27001 certified, GDPR, CCPA and nFADP compliant, and undergoes annual security audits. It automatically deletes files from its servers after one hour.
PDFTrusted: Server-side jobs are cleaned up after processing and deleted within one hour at most. PDFTrusted does not keep a document archive unless you choose to save files to Pro Storage. It does not yet hold an ISO/IEC 27001 certificate.
Verdict: For certified compliance across GDPR, CCPA and nFADP, Smallpdf is strong. For keeping everyday files off servers entirely, PDFTrusted has the edge.
Smallpdf vs PDFTrusted: Devices and Apps
Smallpdf offers mobile and Windows apps; PDFTrusted runs in the browser on any device.
PDFTrustedSome people live in the browser; others want an app on the desktop or phone, with offline access and a scanner. Here is what each product offers beyond its website.
Web, desktop and mobile: Smallpdf has native apps; PDFTrusted needs nothing installed
Smallpdf: Smallpdf offers iOS and Android apps with a PDF scanner, plus a Windows app. The free plan has limited mobile access; Pro unlocks it fully.
PDFTrusted: PDFTrusted has no app to install. Every tool is designed to work in a phone browser with large controls, and on-device tools keep working even on slow connections once the page has loaded. There is no native scanner app yet.
Verdict: Smallpdf wins on apps, especially its mobile scanner. PDFTrusted is a good fit if you would rather not install anything.
Smallpdf vs PDFTrusted: AI Features
Smallpdf has the broadest AI set; PDFTrusted covers chat, summaries and study questions.
PDFTrustedAI tools that summarize long reports, answer questions or translate documents are now a standard part of PDF suites. We compared what each offers and how much you can use it.
What the AI tools can do: Smallpdf adds translation; both offer chat, summaries and questions
Smallpdf: Smallpdfβs AI PDF Assistant includes Chat with PDF, an AI summarizer, Translate PDF and an AI question generator. Pro gives unlimited access, with documents up to 50 MB and 100k words.
PDFTrusted: PDFTrusted offers Chat with PDF, Summarize PDF and a question generator for study and review, each with Standard and Advanced AI. Free covers up to 15 pages; Pro handles up to 200 pages per job. Translation is not available yet.
Verdict: Smallpdf Pro is the stronger AI package, including translation. PDFTrusted covers chat, summaries and questions for less.
Smallpdf vs PDFTrusted: Pricing and Free Plan
PDFTrusted costs about half: $5.99 vs $12 a month, or $49 vs $108 a year.
PDFTrustedAll three have a free plan and a paid plan for individuals. The real difference is what the free plan allows, how much monthly billing costs compared with yearly, and what each paid plan bundles.
