PDFs can be frustratingly large. You scan a few pages of your marksheet, and suddenly the file is 8 MB — way over the 500 KB upload limit on the form you're filling. Or the dimensions are wrong and the portal rejects it outright.
Most "PDF compressor" websites upload your file to their server, process it, and send it back. That works, but it also means some random company has a copy of your marksheet, salary slip, or ID proof on their servers.
FormFocus handles it differently. The entire PDF processing — rendering, resizing, compressing, and re-exporting — happens inside your browser. Your file never touches a server. Here's how to use it.
The PDF Resizer converts each page of your PDF into an image, resizes and compresses that image to fit your target specifications, and then re-assembles everything into a new PDF (or downloads individual images).
This means the output is a raster-based PDF, not a vector one. For scanned documents and photo-based PDFs, there's practically no difference. For text-heavy PDFs, the text won't be selectable in the output — but the visual quality is preserved.
Open FormFocus and click "PDF Resizer" in the navigation bar.
Click "Upload PDF" and select the file. After a moment, you'll see thumbnail previews of all the pages. Large PDFs (say, 20+ pages) may take a few seconds to render.
By default, all pages are processed. But you can choose:
1,3,5 or 1-4 to process specific pagesIf you need the pages to be a specific pixel width or height, enter those values. Leave blank to keep the original proportions. If you only enter a width, the height is calculated automatically to preserve the aspect ratio.
This is usually the most important setting. Enter the total target size in KB — for example, 500 for a 500 KB output. The tool divides this budget across all selected pages and adjusts the compression quality per page to hit the target.
If you're processing 5 pages with a 500 KB target, each page gets roughly 100 KB of budget, but the algorithm is smart enough to give more space to complex pages and less to simpler ones.
You have two choices:
Click "Process PDF." A progress bar shows how far along the processing is. For large PDFs, you can cancel mid-way if needed. Once done, click "Download All" to get the result.
💡 Good to Know:
Yes — that's the ideal use case. Scanned PDFs are already image-based, so the conversion is seamless.
Yes, but the output will be raster images, not selectable text. The text will look the same visually, but you won't be able to copy-paste from the output PDF.
A 5-page PDF typically takes 5–15 seconds. A 50-page PDF might take 1–2 minutes. It depends on your device.
