๐ Formatos aceptados: .PDFWhat rasterising a document means, what is lost on the way, and which resolution to choose
| In the PDF | In the resulting JPG |
|---|---|
| Selectable, searchable text | Pixels: cannot be selected or searched |
| Vectors crisp at any zoom | Fixed resolution: pixelates when enlarged |
| Navigable links and outline | No links |
| Fillable forms | Only the appearance of the form |
| One file with every page | One image per page, separate |
| Separate layers and annotations | Everything flattened into one layer |
Putting a figure, a plan or a chart from a PDF into a presentation or a Word report is far easier with an image.
Social platforms do not display PDFs. Converting the page to an image is the only way for it to show directly in the feed.
Showing a document cover in a listing, a store or a catalogue requires an image.
Rasterising stops content being easily selected and copied. It is not serious security, but it is a practical obstacle.
| Intended use | Guideline resolution | Note |
|---|---|---|
| Thumbnail or preview | 72โ96 DPI | Very light files; small text will not be readable |
| Screen viewing, social media | 150 DPI | A good balance for most cases |
| Reading text comfortably | 200โ300 DPI | Necessary if the document has small type |
| Printing the image | 300 DPI | The print standard; produces large files |
That determines the resolution: a thumbnail and a page for printing are nowhere near the same ask.
Drag it onto the drop zone or click to select it. It is processed inside your browser.
Open an image at 100% and confirm the text reads. If not, retry at a higher resolution.
It is your only version with real text, links and vectors. There is no way back from the JPG.
Yes. A ten-page PDF produces ten independent images, because image formats each hold a single page.
No. Rasterising turns text into pixels. It looks the same but stops being text as far as the computer is concerned: it cannot be selected, copied or searched. Recovering it would require OCR.
Almost always from rendering at too low a resolution. Since the PDF is vector-based, it can be generated at whatever resolution you need: raise the value and the text comes out crisp, at the cost of larger files.
It depends on the content. For pages with photographs, JPG gives far smaller files. For pages with text, tables or line charts, PNG keeps edges clean and avoids the typical JPEG halos.
You can assemble them into a PDF again, but it will be a document made of images: the selectable text, links and original vectors do not come back.
No. All rendering happens inside your browser, so a confidential PDF never leaves your machine at any point.
