Step-by-Step Guide
4 steps · takes under 1 minute
Compress your JPG first
Before converting, run your image through the Image Compressor. Set the quality to 70–80% — this typically reduces a 3MB photo to 200–500KB with no visible quality loss.
Resize to a smaller dimension
If the image is very large (e.g. 4000×3000px from a phone camera), resize it to 1200×900 or 1600×1200 first. Smaller pixels = smaller PDF.
Convert to PDF
Open the JPG to PDF tool and upload your compressed, resized image. The resulting PDF will typically be under 1MB.
If still over 1MB, compress the PDF
Run the output PDF through the Compress PDF to 1MB tool. It applies binary-search JPEG quality targeting to bring it under 1MB.
