Apakah itu PDF (Portable Document Format)?

Memahami format dokumen sejagat yang memelihara kandungan kamu tepat seperti yang dimaksudkan

Fotografi Digital

Fikirkan PDF (Portable Document Format) sebagai gambar digital sebuah dokumen. Sama seperti foto menangkap tepat bagaimana sesuatu kelihatan, PDF menangkap tepat bagaimana dokumen kelihatan - fon, warna, imej, susun atur, dan semuanya. Sama ada kamu buka di komputer Windows, Mac, iPhone, atau tablet Android, ia akan kelihatan sama persis.

Standard Sejagat

Dicipta oleh Adobe pada 1993, PDF telah menjadi standard universal untuk berkongsi dokumen yang perlu kelihatan profesional dan konsisten. Tidak seperti dokumen Word atau fail teks yang mungkin berubah penampilan pada peranti berbeza, PDF direka untuk menjadi 'apa yang anda lihat adalah apa yang anda dapat' - setiap kali, di mana-mana.

Format Serba Boleh

PDF boleh lakukan lebih daripada sekadar paparkan teks dan imej. Ia boleh termasuk borang interaktif, pautan boleh klik, video terbenam, tandatangan digital, perlindungan kata laluan, dan juga model 3D. Kebolehsuaian ini menjadikannya sempurna untuk segala-galanya dari kontrak undang-undang dan kertas akademik hingga katalog produk dan manual arahan.

Percuma & Mudah Diakses

Bahagian terbaik? PDF percuma untuk dicipta, dilihat, dan dikongsi. Kamu tidak perlukan perisian mahal - pelayar web moden boleh buka PDF, dan alat seperti kami membolehkan kamu edit dan manipulasi mereka terus dalam pelayar kamu tanpa sebarang muat turun atau pemasangan.

Soalan Lazim

Segala yang anda perlu tahu tentang PDFDeal

  1. Pergi ke Editor PDFDeal.
  2. Upload your PDF or drag and drop it into the editor.
  3. Use the toolbar to add text boxes, draw signatures, or place annotations on any page.
  4. Resize, reposition, and style each element using the on-canvas controls.
  5. Click Download to save. The edited content is written into the PDF content stream and downloaded directly to your device.

Adobe Acrobat is a desktop application that requires installation and a subscription. PDFDeal runs entirely in the browser using JavaScript PDF libraries, so there is nothing to install and no account required. You can add text and signatures, gabung, pisah, dan compress PDFs the same way, without a subscription or watermarks.

It depends on how the tool processes the file. Most online PDF editors upload your file to a server, process it remotely, and delete it after a delay. PDFDeal works differently: your file is read into browser memory using the JavaScript File API and processed by pdf-lib running locally in your browser tab. No file bytes travel over the network. The downloaded result is generated in the same browser session, so sensitive documents such as contracts or medical records never touch an external server.

Open Alat gabung PDFDeal and upload two or more PDF files. Drag them into the order you want, then click Merge. pdf-lib reads the page trees from each file and writes them into a single output PDF in your browser. The merged file downloads immediately. No files are sent to a server at any point.

Open Alat PDF ke Imej PDFDeal. Each page is rendered onto an HTML Canvas element using PDF.js, then exported as JPG or PNG. You can set the resolution before exporting. The reverse is also available: images are packed into a PDF using pdf-lib, which embeds each image as a page object in the output file.

PDF file size is mostly determined by embedded images and fonts. PDFDeal's compress tool re-encodes embedded images at a lower resolution and applies stream compression to reduce size. Text and vector content are preserved at full quality since they are not image-based. For scanned documents where every page is a raster image, higher compression settings will reduce visual quality, so a medium setting is recommended for most use cases.

Go to PDFDeal's sign tool. You can draw your signature with a mouse or finger, type it in a handwriting-style font, or upload an image of your signature. The signature is placed as an annotation object on the page and embedded into the PDF content stream on download. The output is a standard PDF that opens in any viewer.

Open PDFDeal's protect tool, upload your PDF, and set a password. pdf-lib applies AES-256 encryption to the PDF byte stream in your browser before the file is downloaded. The password is required to open the file in any PDF viewer. You can also set separate owner and user passwords to restrict printing or copying independently of opening.

Yes. Because all processing runs in the browser, PDFDeal continues to work after the page has loaded even if your internet connection drops. PDFDeal is also available as a desktop application for Windows and Mac, which works fully offline without a browser. The desktop app is the same tool but runs as a standalone application, so you can process large files or sensitive documents without any network connection at all.

There is no server-side file size limit because files are not uploaded. The practical limit is your device's available memory. Most modern devices handle PDFs up to several hundred megabytes without issue. Very large files, such as high-resolution scanned documents over 500 MB, may be slow to process depending on your device's RAM and CPU. For extremely large files, the desktop app is recommended as it can use more system resources than a browser tab.
