The job portal has a strict 1MB limit, but whenever I compress my 10-page PDF portfolio, the text and images get horribly blurry. How can I drastically shrink the file size while keeping it sharp? ---

Honestly, shrinking the finished PDF is what makes it blurry. Go back to your source file and re-export with images at 150 dpi instead of 300. Text stays vector so it remains sharp anyway. I do this with our drawing sets all the time, 10 pages should easily fit under 1MB. ---

I had this exact headache sending scanned clinic files under our insurer’s tiny limit. What worked best for me was PDFcap. Just drop your file into the compress tool on [pdfcap.com](http://pdfcap.com); it managed to shrink mine right down whilst keeping the text and images properly sharp. Hopefully that gets you under the 1MB limit. ---

Go back to your original Word file and shrink the images before saving it as a PDF. I learned the hard way with my bakery price lists that compressing a file afterwards just makes everything blurry. Avoid keeping images in full colour if a greyscale version will do. If the portal happens to accept EPUB format, use that instead, since they are naturally tiny. ---

Had the same thing last month trying to get a resume under a limit. Usually the blur comes from images being downsampled too much, so try shrinking the actual photos in your portfolio before placing them in the document, maybe 150 dpi is plenty for screen viewing. Also check if your images are saved as PNG, switching to JPEG for photos alone can cut size a lot without hurting text sharpness at all. ---

@SneakySteel Totally with you on resizing before placing. I also re-export from Word using the print to PDF option, text stays vector and my old laptop handles it fine. ---

@Emily.7 Print to PDF can work well, though some drivers rasterize pages. I’d check the exported file by zooming in on a text-heavy page, then compare its size before uploading. ---

I usually start by checking whether the portfolio pages are scans. For text, export from the original document as a PDF with embedded fonts, rather than compressing a scanned copy. For images, resize them to the actual page dimensions and use about 150 dpi for screen-only viewing; that stays sharp enough for most portals. If it still will not reach 1MB, I would split out any full-page photos or make a leaner 2 to 3 page version, tbh. ---

If it is a scan, run OCR first, then downsample page images to about 150 dpi, use grayscale if color isn’t needed, and save them as moderate-quality JPEGs. Remove hidden data with Acrobat or Ghostscript, then apply lossless optimization. At 1 MB for 10 pages, some image detail must go, so keep a high-resolution master and upload an optimized copy. ---

@Wallabies That matches what I do with claim scans. I set the scanner itself to 150 dpi grayscale before scanning, so there is no downsampling later. If your portfolio started as a Word file, export it again with pictures already resized instead of fixing the finished PDF. Keep the sharp master, upload the lean copy. ---

simplest thing i check first is the original images, drop dpi to 150 and reexport, that usually keeps it sharp enough. i throw my tenant pdfs through pdf24 compress and they come out fine. not sure if it’s the same on mac. ---

Honestly, the blur usually comes from the compressor crushing your images, not the text. What I do is go back to the source file and export with images set to 150 dpi and JPEG quality around 70 percent, which normally lands a 10-pager under 1MB and still looks fine on screen. If you only have the finished PDF, try Adobe’s Reduce File Size or iLovePDF, but rebuilding from the original always comes out sharper.
