If some pages look portrait and others look landscape after you convert images to PDF, do not force the whole batch into one direction first. There are three different problems that can look similar: one source image is sideways, the page orientation was fixed globally, or the image was cropped while being fitted to the page.
With PDF SealBox’s Images to PDF tool, check the thumbnails and rotate only the wrong image, then choose Auto, Portrait, or Landscape and review the Contain or Fill result.
Identify the kind of orientation problem first
| What you see | Check first | What to do |
|---|---|---|
| Only one or two pages are sideways or upside down | The source-image preview | Rotate the individual image instead of changing the whole batch |
| Every page is forced into one direction | Whether Orientation is fixed to Portrait or Landscape | Try Auto for mixed pages; use a fixed direction only for a defined delivery format |
| The direction looks right but the edges are missing | Whether Image fit is Fill | Switch to Contain when all four edges matter |
1. One page is wrong: rotate that image
When most pages are fine and one scan or photo is sideways, page size is rarely the root cause. Changing the entire batch to Landscape may create extra whitespace on pages that were already correct. Find the affected thumbnail and use its rotate-left or rotate-right control.
- Arrange the thumbnails in the intended reading order.
- Check the text, table, or form on each thumbnail—not just the outer shape of the image.
- Rotate only the sideways or upside-down page, then confirm that its position in the batch is still correct.
Use the content as the test: a landscape receipt does not automatically need rotation, and a landscape table may be easier to read when it stays landscape.
2. Portrait and landscape images are mixed: start with Auto
Phone photos, forms, and screenshots rarely share one aspect ratio. PDF SealBox offers Auto, Portrait, and Landscape under Orientation. Auto chooses a page direction from each image, which suits a mixed set of photos or scans. Portrait or Landscape is more appropriate when the recipient requires a consistent page direction.
A fixed direction does not make the content inherently easier to read. It can shrink a wide table onto a portrait page or leave larger side margins around a tall photo. If a fixed delivery format is required, use it—but inspect both the widest and tallest pages before exporting.
3. The direction is fine but the image is cropped: check Contain and Fill
Orientation and image fit solve different problems. Contain places the entire image inside the available page area and may leave whitespace. Fill tries to cover the page area, but it can crop the edges when the image and page ratios differ.
- Receipts, invoices, forms, identity documents, and screenshots: start with Contain because borders, amounts, IDs, and QR codes may matter.
- Full-bleed images where a small crop is acceptable: Fill can work, but preview the widest and tallest pages first.
- Anything where no information may be lost: do not choose Fill just to remove whitespace.
For the broader trade-offs between paper size, margins, and fit, see the related Images to PDF page size, margins, and fit guide. This article keeps those controls brief so the orientation troubleshooting stays focused.
A reliable order of operations
- Open Images to PDF and add JPG, JPEG, PNG, or WebP images.
- Drag the thumbnails into page order; do not assume the filename order is the final order.
- Check each thumbnail and rotate only pages whose content is clearly wrong.
- Use Auto for mixed portrait and landscape pages. Consider Portrait or Landscape when the delivery format requires it.
- Start with Contain. Use Fill only after you confirm that cropping the edges is acceptable.
- Choose the requested paper size and margins for the delivery goal; do not use page size to compensate for a rotation error.
- Before creating the PDF, preview at least the first, last, widest, tallest, and most information-dense pages.
- Reopen the exported PDF and check page count, order, orientation, edges, text, and important numbers before sending it.
Common troubleshooting questions
Why is only one page landscape?
Check that page’s thumbnail and rotate it if the content is sideways. Do not force the entire document into Landscape for a single bad page.
Why does Auto still look wrong?
Auto chooses page direction; it does not fix an upside-down, tilted, distorted, or blurry capture. Rotate a source image when its content faces the wrong way. If the content direction is right but an edge is missing, check whether Fit is set to Fill.
Why does the image not fill the page?
Contain preserves the whole image, so different aspect ratios can create whitespace. Try Fill only when cropping the edges will not remove required information.
Is the text searchable after conversion?
The current Images to PDF workflow places images on PDF pages and does not automatically add an OCR text layer. If searchable or selectable text is required, add a separate OCR step and verify names, dates, IDs, and amounts.
When can I delete the source images?
Wait until you reopen the exported PDF and check page count, order, orientation, cropping, and readability. Then follow your own backup and retention rules.
The short decision rule: rotate one page when one page is wrong; use Auto for mixed directions; choose Portrait or Landscape only for a required uniform format; use Contain when all edges matter; use Fill only when edge cropping is acceptable.
If you need to break up the finished file, use Split PDF. If your goal is to turn PDF pages back into images, use PDF to Image so the two workflows do not get mixed together.
