Build a Portfolio PDF Under an Upload Limit
An image-heavy portfolio has to fit a 10 MB form without looking terrible. Here is where the megabytes go and what to cut first.
Written against the Aug 1, 2026 release·what has changed since
Twenty-four full-bleed images, sixty-two megabytes, and an application form that accepts ten. The instinct is to compress until it fits and hope nobody looks closely. There is a better order, and it starts before any compression at all.
Cut before you compress
Six weak pages removed is a quarter of the file gone at zero cost to quality, and a stronger portfolio besides. Reviewers are not counting pages. Decide what stays while the images are still at full quality, because a decision made after compression is a decision made on degraded evidence.
Resize the images, not just the PDF
Images to PDF embeds your PNG and JPEG bytes into the document. Page fitting changes the display size, not the source pixels, so a 6000 pixel wide JPEG stays a 6000 pixel wide JPEG inside a page that shows it at a quarter of that. This is the single biggest reason portfolio PDFs are enormous.
Export the images at a sensible size from whatever made them first: roughly 2000 pixels on the long edge is generous for a page somebody will read on a laptop. Then build the document with A4 or Letter pages and Contain fitting, unless you genuinely want full-bleed edges cropped, in which case Cover is the one that does it.
Then compress, in two stages
- 1
Lossless first
Compress PDF in Lossless cleanup rewrites the structure and preserves everything visible. On an image-heavy file the saving is usually small, because the weight is in the pictures rather than the plumbing.
- 2
Measure, then decide
The export report gives before and after byte counts. If lossless got you to eleven megabytes, one more step will do. If it got you to fifty-eight, the images are the problem and you should go back and resize them.

Raster only if you must
Raster pages renders each page to a JPEG at your chosen DPI and quality. It is effective and it is visible: fine type softens first, then edges. Judge it at 100 percent on the page with the smallest caption, not on a thumbnail.
Splitting is the last resort, not the first
If the form takes more than one attachment, Split PDF can extract ranges such as 1-6,9 into their own documents. Do it at the very end, from a numbered and verified master, so the parts carry consistent page numbers and you still hold one coherent document to work from when the requirements change.
What goes wrong
- Compressing first and cutting pages afterwards, so the surviving pages are degraded for no reason.
- Judging quality on the thumbnail grid, where everything looks fine.
- Rasterising a portfolio that also carries a written statement, which loses the text a reviewer might search.
- Maintaining four near-identical versions instead of one master you derive the parts from.
- Screenshotting pages to shrink them, which adds a generation of loss and usually adds size as well.
The short version
- Remove weak pages before compressing anything.
- Resize the source images; the conversion embeds them as given.
- Lossless cleanup rarely helps an image-heavy file, and its report tells you so.
- Judge raster quality at 100 percent on the page with the smallest text.
- Split last, from a verified master, only if the form accepts more than one file.
Measure what the file actually costs
Choose lossless cleanup or smaller raster pages with an explicit quality trade-off.
