Edit PDF

Add text with font family, size, bold, italic, underline, strikeout, alignment, background, color, opacity and rotation. Add JPG, PNG or WebP images, rectangles, ellipses, lines, arrows, highlights and freehand strokes. Shape fill and border colors can be set independently.

Select an addition to reveal its resize handles. Corner handles also scale text size; side handles change the text box and wrapping. Line and arrow endpoints can be dragged independently. Use the round handle to rotate or the rotation control in the contextual toolbar. Hold Shift to preserve proportions or snap rotation. Geometry is adjusted directly on the page, without coordinate fields. Formatting and text changes apply automatically; the caret stays in the active field.

Move selections by dragging or arrow keys. Layer controls, duplication and Undo/Redo apply to added artwork. Keyboard shortcuts work when focus is outside text inputs. Existing PDF content stays below new additions.

Edit added text directly on the PDF, not in a separate text box. Double-click a text addition to resume typing, use Enter or F2 when it is selected with canvas focus, or tap an already selected text addition on a touchscreen. Multiline text and language input methods are supported. Escape or Ctrl/Command+Enter finishes editing. The contextual toolbar changes formatting while preserving the on-page text and caret. This does not edit original PDF text.

New text, shapes, symbols, comments and images start in the center of the visible PDF area. New lines and arrows start horizontal; drag their endpoints to change direction. Freehand strokes stay where you draw them and finish deselected. Select a stroke manually to show its box; it can be moved and rotated, but does not show resize handles. Drag anywhere inside a selected, rotated bounding box to move an addition. Duplicate keeps its small offset from the original. How to use is beside Change PDF after loading, when enabled by the administrator.

The Shapes menu includes eight symbols: smiling, sad and neutral faces, a heart, an exclamation mark, a question mark, a check mark and a cross. Each supports color, opacity, resizing and rotation, with the same appearance in the preview and exported PDF. Symbols are drawn locally rather than relying on platform emoji fonts.

Drag the grip beside an item in the Added elements panel to reorder layers on that page. The top item appears in front. Mouse, touch and pen are supported. With keyboard focus on a grip, press Space to pick up the layer, use arrow keys or Home/End to move it, then Enter to drop or Escape to cancel. Each completed reorder is one Undo/Redo step; other pages are unchanged.

Add an invisible clickable region using the selected element area or the whole page, with an HTTP(S) address, a single-recipient mailto address or a page in the same PDF. Resize and position a temporary shape to define an exact area, capture its bounds for the link, then remove the shape if it is not needed. No URL is opened while editing. Add top-level page bookmarks or embed permitted supporting files without opening them. Attachments accept PNG, JPEG, WebP, GIF, BMP, TIFF and AVIF images, DOCX, PPTX and PDFs. Executables, SVG, macro-enabled Office files and unsafe active content are rejected. Use at most five attachments, 20 MB each and 100 MB combined.

Use the lists to edit or remove document additions before export; their changes are separate from the artwork Undo/Redo history. Existing valid bookmarks and flat attachment indexes are preserved. Malformed, unsafe or overly complex indexes are rejected when adding to them. PDF readers differ in bookmark, attachment and comment support. Embedded files are not virus-scanned.

Added text and artwork are flattened transparent image overlays. They support fonts and scripts available on your device, but are not selectable text in the exported PDF. Original page content is retained, not rasterized or rewritten. Existing text, fonts and images cannot be directly modified. Text wrapping and clipping follow the selected box dimensions. Comments become standard PDF text-note annotations.

This is not a redaction tool. Drawing a box over sensitive text does not erase the original data. Use a dedicated true-redaction workflow when removal is required. Signed PDFs are rejected because editing can invalidate signatures. Form filling and visual signing are available as separate Helphonic tools; certificate signing is not supported.

One PDF up to 20 MB, at most 50 source pages, 200 added elements, 20,000 drawing points and 200 existing form fields. Inserted images are limited to 20 files, 8 MB each, 20 MB combined, 16 million pixels per image and 32 million pixels combined. Rendered overlays are limited to four million pixels per page; the document and artwork output budget is 60 MB. Up to five permitted attachments can add 20 MB each and 100 MB combined; the attachment-aware PDF output ceiling is 160 MB. These are separate from the shared 200 MB combined download ceiling.

Password-protected, XFA and digitally signed PDFs are not supported. Existing page rotations and crop boxes are respected for artwork. Extremely large or malformed pages are rejected. Work is held only in page memory, not autosaved. Previewing and editing do not use an operation; a confirmed export does.

Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.

Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.

If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.
