JPG to PDF Under 500KB
Build a multi-page PDF from your photos, automatically compressed to fit.
A 500KB cap is common on portals that expect a short multi-page PDF rather than a single photo — a scanned form with a few pages, a small set of ID documents, or a handful of receipts, where 100KB would be too tight but an uncompressed multi-megabyte file is still too large. This tool builds a PDF from your images and, if the result comes out over 500KB, automatically re-compresses each embedded photo and rebuilds the file until it fits — using the same binary-search JPEG compression this site's photo resizer relies on, just applied across every page in the PDF rather than one image at a time. Because the budget is larger than our 100KB tool, image quality generally holds up noticeably better here, especially for batches of two or three photos. As always, everything happens locally in your browser — your files are never uploaded anywhere, and the final size actually achieved is always shown to you.
How it works
- 1
Drop or select your images (JPEG, PNG, or WebP).
- 2
Click "Build PDF" — each image is embedded and the file is compressed toward 500KB automatically.
- 3
Download the finished PDF; the achieved size is always shown.
Frequently asked questions
Why choose the 500KB version instead of the 100KB one?
500KB leaves noticeably more room per image, so it's the better choice whenever the form's limit allows it — you'll generally get sharper results, especially with more than one or two photos in the batch.
Does more images mean lower quality per photo?
Yes — the 500KB budget is divided across every image in the batch, so five photos each get less room than two would. Removing unnecessary pages is the easiest way to raise per-photo quality.
Can I use this for scanned documents instead of photos?
Yes — this works the same way for scanned pages as it does for regular photos, though very text-heavy scans may look best if you keep contrast high before uploading, since text is more sensitive to compression than photographic detail.
