What image formats can I combine into PDF?
Diwadi supports JPG, JPEG, PNG, HEIC (iPhone photos), WebP, TIFF, and BMP formats. You can mix different formats in a single PDF — for example, combine iPhone HEIC photos with PNG screenshots in one document.
Can I reorder pages before creating the PDF?
Yes. After adding your images, you can drag and drop to reorder them before generating the PDF. The final page order in the PDF matches the order you set in the app.
Does it compress the images when creating the PDF?
You can optionally enable compression when combining images. The 'Compress output PDF' option applies smart compression to reduce the final file size while maintaining acceptable image quality. Leave it unchecked to preserve full image quality.
What's the maximum number of images I can combine?
There is no limit on the number of images you can combine. Diwadi runs locally on your machine, so you are not constrained by server-side upload limits or quotas. Combine 5 images or 500 — it works either way.
Can I set the page size for the output PDF?
Yes. Choose from standard page sizes like A4 (210 × 297 mm) or US Letter (8.5 × 11 in), or select 'Fit to Image' to have each page sized exactly to its source image dimensions. Fit to Image is ideal when you want pixel-perfect pages.
Does converting images to PDF reduce quality?
Without compression enabled, image quality is preserved at full resolution. If you enable the 'Compress output PDF' option, some quality reduction may occur to reduce file size. For submission documents or official records, leave compression off to retain original quality.
Can I combine HEIC photos from iPhone into PDF?
Yes. Diwadi natively supports HEIC files, the default photo format on iPhones and iPads. No prior conversion to JPG is needed. Just add your HEIC photos directly and they will be embedded in the PDF correctly.
Is there a file size limit for input images?
No. Because Diwadi processes everything locally on your device, there are no file size restrictions on input images. You can add large RAW-style photos, high-resolution scans, or multiple large TIFF files without any upload limits.
Can I mix different image formats in one PDF?
Absolutely. You can add JPG, PNG, HEIC, WebP, TIFF, and BMP images in any combination and Diwadi will combine them all into a single PDF. The output format is standard PDF, readable on any device.
Does it preserve image metadata (EXIF) in the PDF?
EXIF metadata such as GPS coordinates, camera model, and capture date is embedded in the source image but is not typically carried into the PDF output. If preserving EXIF data is critical, keep your original image files separately alongside the generated PDF.
