Online Toolsz vs Smallpdf: free PDF tools with and without uploading
Comparing Online Toolsz and Smallpdf for merging, splitting and everyday PDF work: in-browser processing vs uploads, accounts, features and which to use when.
Feature comparison
| Feature | OnlineToolsz | Alternative |
|---|---|---|
| Processing model | PDF page tools run in the browser, so the file stays on your device. OCR to Word is the exception and uses our server plus Adobe PDF Services. | Cloud-based: in the web app, files are uploaded to Smallpdf for processing. |
| Getting started | Open a tool page and add files. No sign-up at any point. | Some tasks work straight away; an account and paid plans add more. Check their current plans. |
| Merging | Add two or more PDFs, see a thumbnail of each, drag them into order and download one file. | Merging inside a larger document workspace, alongside its other tools. |
| Breadth of features | Core page tools, image conversions, OCR to Word and a basic editor, plus QR code and text to speech utilities. | A broad document suite, including Office conversions, e-signatures and richer editing. |
| Platforms | Any modern browser on desktop or mobile. | Web app plus desktop and mobile apps. |
| Collaboration and history | None. Nothing is stored, so there is no shared workspace or file history. | Account-based storage and options for teams and businesses. |
| Best fit | One-off private jobs and people who don't want another account. | Daily document work, signing, and teams already on the platform. |
Two different ideas of a PDF tool
Smallpdf is built as a document workspace: you upload files, work on them in the cloud, and can come back to them through an account. Online Toolsz is closer to a set of single-purpose utilities. You open the tool you need, your browser does the processing, you download the result, and nothing is kept. Neither is a cut-down copy of the other; they suit different habits. If PDFs are part of your job every day and you share them with colleagues, a workspace has real advantages. If you merge two files twice a month, a workspace can feel like more than the task needs.
Merging PDFs step by step on Online Toolsz
Open Merge PDF and drop in two or more files. Each file appears with a thumbnail of its first page, so you can tell 'invoice-final' from 'invoice-final-2' without opening either one. Drag the files into the order you want, merge, and download. Pages are copied as they are, so text stays selectable and images are not recompressed by the merge. Because everything runs in the browser, a large batch is limited by your device's memory rather than by an upload size. If you only need some pages from a file, run Split PDF first to extract them, then merge the pieces.
Where Smallpdf has the edge
Smallpdf's strengths are breadth and polish. It handles conversions between PDF and Office formats, electronic signatures and editing that goes well beyond what a browser-only toolkit offers, and it has desktop and mobile apps for people who prefer them. For teams, an account-based platform also means shared access and one consistent place for documents. If your organisation already pays for it, using it for everything is often the simplest option. Plans, usage limits and included features change from time to time, so check their current pricing page rather than relying on what a third party says.
When uploading is a real concern
Some files carry more risk than others. A signed lease, a payslip, a medical report or a client's identity documents may come with contractual or legal duties about where the data goes. A cloud service can be well secured, but uploading still means a copy exists, at least for a while, on someone else's systems, and you are relying on their policies. With in-browser processing that question does not arise for the supported tools. On Online Toolsz that covers merge, split, compress, rotate, remove, organize, grayscale, repair, editing and image conversions. OCR PDF to Word is different: it uploads the file to our server and to Adobe PDF Services.
Accounts, prompts and small frictions
For a quick job, friction is mostly about the steps around the task: sign-up prompts, waiting for uploads, and being asked to pick a plan. Cloud services ask for accounts for part of what they offer, partly because that is how they pay for the servers that process your files. Online Toolsz is funded by advertising and has no accounts at all, so there is nothing to sign in to. The flip side is that there is no saved history either. Once you close the tab, the result exists only where you downloaded it, so keep your originals until you have checked the output.
Working on a phone
Both work in a mobile browser. On Online Toolsz the processing uses your phone's own memory and processor, which is fine for typical forms and a handful of photos, but can get slow with very large scans or dozens of files. Smallpdf's dedicated mobile apps may feel more natural if you deal with PDFs on your phone every day, particularly alongside camera scanning. For an occasional job, like merging a boarding pass with a hotel confirmation before a trip, the browser is usually enough, and you skip installing yet another app.
How to decide
Go with Online Toolsz when the task is a common page operation, the file is sensitive, you don't want to create an account, or you only need PDF tools now and then. Go with Smallpdf when you need Office conversions, e-signatures, richer editing, native apps, or a shared workspace for a team. If you are unsure, try the task in the browser first. If the result is what you need, you are done. If you hit a missing feature, that tells you a fuller suite is worth it for that particular job, and you have lost nothing but a minute.
Will merging in the browser reduce quality?
No. Merging copies existing pages into a new file without re-rendering them, so text, vector graphics and images look exactly as they did before. The merged file ends up at roughly the combined size of the inputs. If it is then too large for an email or an upload portal, that is a separate step, and for scan-heavy files you may need a tool that recompresses images. A quick check after merging is worthwhile anyway: scroll through once to confirm the order and that no page was left out.
Can I use both?
Of course. Many people keep a browser tool for quick private jobs and use a cloud suite for conversions or signing. The output is a standard PDF either way, so a document merged on Online Toolsz can be signed elsewhere, and a file converted elsewhere can be split or reordered here. A sensible split is to do the page work on sensitive files locally first, removing anything the other service doesn't need to see, and upload only the final pages that need a feature the browser lacks.
