Edit
Browse all edit toolsediting PDFs with the SimplePDF free editor, where the features page documents adding text anywhere in the document with an optional white background, adding checkboxes, uploading images, drawing or uploading a signature, and automatic detection of existing form fields for quick editing; the editor does not claim to rewrite the document's existing body text and the white background is not a redaction. The scope records the documented add-text, checkbox, image, signature and form-field operations in the browser editor, makes no general text-editing, OCR or redaction claim, and keeps page merge/reorder operations in the merge scope
Merge
Browse all merge toolsmerging and organising pages with the SimplePDF free editor, where the features page documents merging multiple PDFs into one document, rearranging pages by drag and drop, rotating page orientation, deleting pages and inserting blank pages or additional PDFs; the home FAQ also addresses merging PDF files by loading them and downloading the result. The scope records the documented merge, reorder, rotate, delete and add-page operations in the browser editor and makes no preservation or fidelity guarantee for signatures, forms, links or annotations
Sign
Browse all sign toolssigning PDFs with the SimplePDF free editor, where the features and signature help pages document drawing or uploading a signature, or typing a signature, and placing it on the document in the browser; the vendor describes simple electronic signatures and does not document certificate-backed or cryptographic digital signing. The scope records the visual electronic signature insertion in the browser editor and makes no certificate-authority, validation, timestamp or independent legal-validity guarantee
Convert
Browse all convert toolsconverting PDFs with SimplePDF, where the PDF to Web Form page documents uploading any PDF, turning it into an online web form, sharing a link and collecting submissions through a dashboard, with no coding required. The scope records the documented PDF-to-web-form conversion workflow and the paid dashboard/submission path, and makes no Office, image or generic file conversion claim, no OCR claim and no conversion fidelity guarantee
Where your files are processed
Mixed - depends on version and feature
The vendor's own documentation separates them. On the device: Free browser editor. On their servers: Paid dashboard and submission workflows, API (Premium). A single answer for the whole product would be wrong for one of them.
The free editor processes the PDF in the browser and does not send the document to SimplePDF servers. Paid workflows have server-side paths: accounts, dashboard, hosted submissions without bring-your-own-storage, email and webhook notifications, and the API on the Premium plan.
With bring-your-own-storage, completed files go from the browser to the customer's S3, Azure Blob Storage or SharePoint storage using presigned URLs. The current operator is SimplePDF B.V., Pieter Baststraat 24H, 1071 TX Amsterdam, Netherlands; Tree Social OÜ (Estonia) is historical and was replaced in October 2026.
What it does
SimplePDF is a browser PDF editor and document-workflow service operated by SimplePDF B.V., Pieter Baststraat 24H, 1071 TX Amsterdam, Netherlands. The company replaced Tree Social OÜ as operator in October 2026, and the terms now use Netherlands law.
The free editor fills, edits, signs and merges PDFs in the browser: it adds text, checkboxes and images, detects existing form fields, supports drawn or uploaded signatures, merges PDFs and reorders, rotates, deletes and adds pages. Editing is client-side, no account or payment is required for the free editor, and the finished document is generated and downloaded on the user's device.
Paid plans add hosted submission collection, a dashboard, email and webhook notifications, embeds, custom branding, bring-your-own-storage and, on Premium, API access; those workflows involve server-side accounts, storage and notifications. Current prices are published in USD only: Free, Basic USD 99 per month, Pro USD 349 per month and Premium USD 899 per month, with the annual toggle amounts not present in the served page.
The embed SDK is a separate MIT-licensed repository.
Best for
Individuals who need to fill, sign, merge or lightly edit a PDF privately and for free, and businesses that want an embeddable form-filling workflow pointed at their own storage.
Worth knowing
The live operator is SimplePDF B.V. in Amsterdam, Netherlands, and the current terms use Netherlands law. The privacy and terms version history say SimplePDF B.V. replaced Tree Social OÜ (Estonia) in October 2026, so Tree Social OÜ is historical rather than current.
The free editor is genuinely client-side and requires no account: its documents are processed in the browser and the finished file is generated locally. Paid workflows are different: accounts, the dashboard, hosted submissions without bring-your-own-storage, email and webhook notifications, and API access on Premium involve server-side paths, and completed files on paid plans without bring-your-own-storage are stored by SimplePDF.
Do not read the free-editor locality claim as covering every paid workflow. Pricing is USD only: Free, Basic USD 99 per month, Pro USD 349 per month and Premium USD 899 per month.
There is no GBP figure, so priceFromGbp is null and priceBasis is unknown; the previously recorded GBP 73.43 was a conversion of USD 99 and is removed. The annual toggle amounts were not present in the served page, so no annual price or monthly equivalent is asserted.
API access is listed on Premium, but whether the API plan is self-serve was not established; the pricing page offers a free trial but the API reference page itself rendered as a JavaScript shell. The free editor is a filler and light editor, not a document-processing suite: it has no OCR, no compression and no password protection.
Its white-out tool places a white background over text rather than removing it, so it is not redaction. Signatures are visual drawn or typed signatures, not certificate-backed digital signatures.
The PDF-to-web-form conversion turns an uploaded PDF into an online form with a dashboard, links and submissions; it is not Office, image or generic file conversion, and no conversion fidelity is claimed. The embed SDK is MIT-licensed as a separate repository; that licence is not applied to the hosted service.
The supported surfaces are the browser editor, the JavaScript/React/iframe embed, the API and the listed Chrome, Bubble and WordPress integrations; there is no desktop, mobile-native or other hosted conversion product.

What the redaction verdict rests on
From the vendor's own documentation, read 4 October 2026. Not tested by us.
What that does not establish
The vendor documents a white-out tool, and a white-out covers text rather than removing it. Secure removal of the underlying content has not been established by this audit, so this is recorded as no redaction rather than as an absence of any related feature: the guide exists and says what the tool does.
What the vendor says
Claims are labelled rather than repeated as fact. Where we have checked something ourselves, it says so and shows when. Checked means we read the vendor's own page and it says what we recorded - not that we tested the behaviour, unless the note says we did.

“On every plan, including the free editor, SimplePDF processes PDFs entirely in the user's browser.”
Checked by us - the source says this Read 22 September 2026
Confirmed verbatim, and this one is worth reading in full because the page qualifies it carefully rather than overclaiming. "Processing: always happens in the browser" is stated as a separate line, and the surrounding text explains the mechanics: no document content is sent to SimplePDF servers while filling, signing or modifying, so "SimplePDF has no server-side copy of the PDF to access or expose".
It then draws the boundary honestly - the Pro plan can upload completed documents directly from the browser to storage you own using presigned URLs, and "SimplePDF never stores the file". This is the strongest local-processing claim the index holds after SnackPDF's tested one, and unlike most it distinguishes the editing phase from the storage phase.
Not tested; our locality instrument does not currently cover it.

“Trusted by 100 000+ people worldwide”
Checked by us - the source says this Read 22 September 2026
Confirmed verbatim, including the space-separated thousands separator: the page reads "Trusted by 100 000+ people worldwide". That formatting is a localisation tell rather than an error, and it is recorded as the vendor wrote it.
As with the other social-proof claims in this batch - Adobe's 5 million companies, Docusign's 1.9 million, PDF Expert's 30 million, SignWell's business count - no source or date accompanies the figure and none was sought, because the vendor publishes no method behind it. Recorded as the vendor's assertion.
It is a vendor figure and it is reported as one: the number is theirs, its method is not published, and we have not audited usage. Whether it looks plausible is not a finding.
