Why Edit a PDF in Your Browser Instead of Desktop Software?
Traditional PDF editors like Adobe Acrobat are expensive and require installation. Browser-based editors like PdfDocShift's Edit PDF tool achieve the same result for the most common tasks — adding text, inserting images, drawing annotations — in seconds and at zero cost.
When Should You Use White-out vs Redact PDF?
The White-out tool in the editor is a visual cover — it draws an opaque white rectangle over content, which gets baked into the output image layer when you download. This is ideal for covering up errors, placeholder text, or cosmetic edits on a final document. If you need to permanently and verifiably remove text from the PDF data layer (so it cannot be retrieved by selecting/copying the text or inspecting the file), use the dedicated Redact PDF tool instead — it deletes the text from the content stream entirely and replaces it with a solid black mark.
What Happens to Page Quality When I Add Annotations?
Each page is rendered from the original PDF at up to 1.5× scale using PDF.js, producing a high-resolution canvas. When you download, that canvas is embedded as a PNG inside the output PDF at the same pixel dimensions. The resulting file is a raster (image-based) PDF, meaning text on annotated pages becomes an image rather than selectable text. For pages with no annotations, the original vector content is preserved. If you need the output to remain fully text-searchable after editing, run it through the OCR PDF tool after downloading to restore the text layer.
Edit PDF questions
Common questions about annotating and editing PDF files online.
Yes. Select the Text tool in the toolbar, then click anywhere on the PDF page. A text box will appear — double-click it to edit the content. Choose your font size and colour in the toolbar. The text is baked permanently into the output PDF when you download.
Use the White-out tool. Draw a rectangle over the text you want to hide — it places a white (or any colour) opaque box on top. On download, it is permanently merged into the page image. For legally admissible redaction that removes the underlying text data entirely, use the dedicated Redact PDF tool.
Yes. Click the Image tool, then choose a JPG, PNG, or WebP file from your device. The image appears on the current page. Drag it to reposition and drag the corner handles to resize. You can add multiple images across different pages.
Yes. Use the ‹ and › buttons in the toolbar to navigate between pages. Each page has its own annotation layer. Your work on each page is saved as you navigate. When you click Download PDF, all pages — annotated and original — are included in the output file.
No. The entire editing session runs locally in your browser. Your PDF is read from your device, rendered with PDF.js, annotated with Fabric.js, and the output PDF is assembled with pdf-lib — all client-side. No file is uploaded to any server during the edit session. The only time network activity occurs is loading the page itself.
Yes. Click the Undo button in the toolbar to step back through your changes. Redo is also available. The undo history is kept per page and holds up to 50 steps per page.
Pages that have annotations are re-rendered as high-resolution PNG images (at up to 1.5× scale) and embedded in the output PDF. Pages with no annotations are reproduced from the original at full resolution. The overall visual quality is very close to the original, but annotated pages become image-based rather than vector/text-based. If text searchability is important, run the output through OCR PDF afterwards.
