Gratis tools voor PDF, afbeeldingen en Markdown — geen software te installeren, geen watermerken op uw bestanden en bestanden worden nooit langer dan 60 minuten bewaard.
ACE PDFMD is een webgebaseerde toolkit met meer dan 70 tools voor het werken met PDF-, afbeeldings- en Markdown-bestanden — samenvoegen, splitsen, comprimeren, converteren, bewerken, ondertekenen, OCR, redigeren en meer. Gebouwd om een echt gratis, snelle en privacyvriendelijke alternatief te zijn.
Ja. Iedereen kan ACE PDFMD gebruiken zonder zich aan te melden — anonieme bezoekers krijgen 10 gratis taken/downloads per dag. Een gratis account aanmaken verhoogt dit tot Onbeperkt. Geen creditcard vereist. Een betaald Pro-plan ($2,99/maand of $24,99/jaar) verwijdert alle dagelijkse limieten.
Nee. Elk tool werkt in de browser. Er is niets te downloaden of installeren.
Veel tools uploaden uw bestand niet. Voor servertools reist het via HTTPS en wordt verwijderd binnen 60 minuten. Privacybeleid.
Er wordt geen AI-API van derden gebruikt om uw documenten te verwerken. Alle conversies, OCR en bewerkingen draaien op zelf-gehoste open-source software — uw inhoud wordt nooit verzonden naar OpenAI, Google Gemini of een andere AI-provider.
Zie onze volledige Prijzen-pagina voor een vergelijking van dagelijkse limieten, bestandsgroottes en prijzen.
De meeste gratis PDF-sites leggen u zeer agressieve beperkingen op, verstoppen tools achter betaalmuren of monetariseren uw documenten stilzwijgend. ACE PDFMD houdt zijn Anonieme en Gratis niveaus echt bruikbaar voor dagelijkse taken, is transparant over wat wordt opgeslagen en rekent een van de laagste Pro-prijzen — $2,99/maand — zonder verborgen kosten.
ACE PDFMD is gebouwd op verschillende open source-projecten en is ze dankbaar: pikepdf (MPL-2.0), pdfplumber (MIT) en pypdfium2 (Apache-2.0) voor het lezen, weergeven en bewerken van PDF's, img2pdf (LGPL-3.0) voor verliesvrije afbeelding-naar-PDF-conversie, en Tesseract OCR en LibreOffice op de server. In je browser verzorgen KaTeX (MIT), Turndown (MIT) en Mammoth.js (BSD-2-Clause) de weergave en conversie. PyMuPDF (AGPL-3.0) wordt nergens in het project meer gebruikt. Onze dank aan de auteurs en communities achter deze projecten.
