Quick symptom table
| Symptom | Likely reason | First thing to try |
|---|---|---|
| Text looks fuzzy | Source is blurred or quality is too low | Inspect the original at 100%, then create a High-quality test. |
| Image edges are missing | Fill the page is cropping mismatched proportions | Choose Fit entire image. |
| Large white borders | Image and page shapes differ | Try Auto orientation, a smaller margin or Fit to image. |
| Page is sideways | Image pixels or metadata have unexpected rotation | Use the rotate control on the preview. |
| Browser slows or stops | Large images exceed comfortable device memory | Use a smaller batch and close other heavy tabs. |
| Image is rejected | Unsupported or invalid file | Export a fresh JPG or PNG copy from a trusted editor. |
| No download appears | Browser blocked or moved the download | Check Downloads and site download permission. |
The PDF looks blurry or text is hard to read
Open the source image itself and zoom to 100%. If letters are already soft, doubled by motion or hidden in shadow, the converter cannot recover them. Retake the photograph in even light, clean the lens and tap to focus on the smallest important text.
If the source is sharp, create one High-quality test page. Use Fit entire image and avoid placing an extremely wide or tall image on a page that makes it tiny. Long screenshots are a common example: divide them into logical sections before conversion so each segment receives enough page area.
- Use the closest available copy to the original.
- Avoid images that have been compressed by messaging apps.
- Select High quality when fine print, diagrams or artwork matter.
- Judge at 100% zoom and, if needed, on a test print.
The PDF crops edges—or leaves borders you did not expect
Cropping is usually the result of Fill the page. The converter enlarges the image until the entire page is covered, which means excess width or height falls outside the page. Choose Fit entire image to preserve all edges.
Empty borders have the opposite cause: the full image fits inside a differently shaped page. They are not a conversion error. Reduce the margin, use Auto orientation, or choose Fit to image if natural proportions are more important than standard paper dimensions.
For receipts, forms and identification records, visible edges and complete content matter more than filling the page attractively.
A page is sideways or has the wrong orientation
Rotation changes the content; orientation changes the PDF sheet. First use the rotate button on the image preview until words read normally. Then choose Auto, Portrait or Landscape for the page.
Some camera files store direction as metadata rather than permanently rotating the pixels. Browsers usually interpret that correctly, but an image edited or transferred through another program may behave differently. Exporting a fresh JPG or PNG copy after visually rotating it in your device editor can normalize the file.
- For a mixed set, rotate each source correctly and choose Auto orientation.
- For a uniform printed document, rotate each source correctly and force Portrait.
- If only one image misbehaves, isolate it in a one-page test before reconverting the whole batch.
The PDF is too large, or conversion slows down
Local conversion uses your device's memory. Forty modern camera photographs can require much more working memory than their compressed file sizes suggest, because each image must be decoded while the PDF is assembled.
- Try a one-image test
This separates a damaged file from a batch-size problem.
- Split the batch
Create logical parts of 10–20 images and see whether performance stabilizes.
- Close other memory-heavy tabs or apps
Video, design tools and large documents may compete for the same device resources.
- Prepare smaller source copies when appropriate
Crop unused background or resize copies for screen-only delivery, while retaining originals.
- Use Balanced or Smaller quality
Inspect readability rather than assuming the smallest result is acceptable.
AnyImageToPDF currently limits selection to 40 images, 25 MB for each image and 200 MB for the batch. A device can still reach its practical memory limit before those input limits, especially with very high-resolution images.
An image will not load
The current converter accepts valid JPG/JPEG, PNG and WebP images. A file may have a familiar extension while its contents are incomplete or use a different format. Try opening it in your normal photo viewer first.
HEIC/HEIF, TIFF, SVG, RAW camera files and animated images are not accepted by the current interface. Export a normal JPG or PNG copy using your device's built-in tool or another trusted application. For an animated source, decide which single frame you actually want to document.
Renaming “photo.heic” to “photo.jpg” leaves the underlying format unchanged. Use a real export or conversion function.
The PDF was created, but you cannot find the download
- Open the browser's Downloads list; mobile browsers may show it behind a menu.
- Check whether the browser asked for permission to download a file.
- Look in the device's default Downloads folder, Files app or browser-specific folder.
- Use Download again in the completion dialog if the first download was dismissed.
- Make sure private-browsing or storage restrictions are not preventing downloads.
If the interface stops before the completion message, reload the page and test with one small known-good JPG. Add the remaining images in groups to identify whether a particular file or total batch size triggers the problem.
