A small business owner scans eight receipts for a monthly expense report. Each scan is a separate JPG file. The accountant wants one PDF. Emailing eight image attachments is messy; most email clients impose attachment limits and recipients have to open each file individually. The obvious solution is to combine all the images into a single multi-page PDF before sending.
Students do this for assignment submissions. Freelancers do it for portfolio packs. Medical patients do it for insurance claim paperwork. The problem is that most free online tools require uploading personal photos and scanned documents to a remote server. For anything sensitive, that is a real concern. This tool converts images to PDF entirely in your browser. Nothing leaves your device at any point.
How It Works
- Add your images: Drag and drop multiple image files onto the upload area, or click to browse. The tool accepts PNG, JPG, GIF, WebP, and BMP files in any combination. A live count shows total images added and combined size. Use the Add More button to bring in additional files after the initial selection.
- Set order and PDF settings: Reorder images using the Move Up and Move Down buttons, or sort the full list by file name or file size. Choose a page size: Auto (each page fits its image exactly), A4, US Letter, or Legal. Set orientation to Auto, Portrait, or Landscape. Choose image quality: High for maximum sharpness, Medium for a balance of size and quality, or Low for the smallest possible output file. Toggle Fit Image to Page to preserve the aspect ratio without cropping, and Center Image on Page to position each image in the middle of its page.
- Convert and download: Click Convert to PDF. The browser processes each image in sequence, embeds them as image objects on individual pages in your specified order, and produces a single multi-page PDF. Download the file immediately.
Compatibility & Support
Supported Input → Output Formats
- Input image formats: PNG, JPG/JPEG, GIF, WebP, BMP (mixed formats accepted in the same batch)
- Output: Single multi-page PDF with one image per page
- Page sizes: Auto (fit to image), A4 (210 x 297 mm), US Letter (8.5 x 11 in), Legal (8.5 x 14 in)
- Quality levels: High (best quality, larger file), Medium (balanced), Low (smallest file)
Unsupported Formats
HEIC, TIFF, SVG, and RAW image formats are not accepted as direct input. Convert HEIC photos (typical iPhone output) to JPG first before adding them to the batch. Animated GIFs embed only the first frame as a static image in the PDF. PDF files themselves cannot be added as input images; use the Merge PDF tool for combining existing PDF documents.
File Size Limits
All processing is fully offline in the browser, so no server-imposed file size cap applies. The tool handles batches of any size that a modern browser can load into memory. Very large high-resolution image sets may take a few extra seconds to process on older hardware, but will complete without any file size restriction.
Who Should Use This Tool?
- Students: A student scanning handwritten lecture notes page by page on a phone camera can combine all JPG scans into one ordered PDF for submission, rather than emailing or uploading a folder of numbered image files.
- Freelancers & Designers: A photographer delivering a curated set of 15 edited portfolio images to a client can pack them into a single PDF with Auto page sizing so each image fills its page at full resolution, ready to present or print.
- Office Professionals: An accounts clerk collecting 20 scanned vendor receipts during a week can combine all JPG scans in date order into one PDF for the monthly expense filing, without uploading private financial documents to any online platform.
- Developers: A developer building a document intake workflow can use this tool to generate test multi-page PDFs from sample image sets quickly, validating rendering and page sizing behavior before implementing image-to-PDF logic in production code.
Key Features
Here's what separates this tool from generic alternatives:
100% Offline Processing
Your images never leave your device. Everything runs locally in the browser, making it safe to process medical records, financial scans, personal photos, and confidential business documents.
Full Page Order Control
Move pages up or down individually, or sort the full batch by name or size in one click. Getting the page order right before converting is critical for scanned multi-page documents, and this control is built in rather than an afterthought.
Four Page Size Options
Auto sizing fits each page to its image dimensions with no borders. A4, Letter, and Legal give you standard paper sizes for professional or official submissions where a consistent page size is required throughout the document.
Three Quality Levels
High quality preserves maximum image sharpness for portfolios and official documents. Low quality produces the smallest file for email attachments with strict size limits. Medium hits the right balance for most everyday use.
Mixed Format Batches
PNG, JPG, GIF, WebP, and BMP files can all be added to the same batch without any pre-conversion. A folder of mixed-format scans and screenshots converts into one clean PDF in a single operation.
Center and Fit Controls
Fit Image to Page scales images to fill the selected page size while preserving aspect ratio. Center Image on Page ensures consistent visual alignment across pages of varying image dimensions.
Why This Tool Beats the Alternatives
- No account, email, or signup required at any point.
- No watermarks added to the output PDF.
- No server upload; personal photos and private scans stay on your device throughout the entire conversion.
- Mixed image format support in a single batch; many tools restrict to JPG or PNG only.
- Four page size options including Auto sizing, which most basic converters do not offer.
- No daily conversion limits or paid tier required to process large batches.
Pro Tips
- For scanned documents that need to look like official paperwork (expense reports, application forms, legal submissions), set page size to A4 or Letter, enable Fit Image to Page, and choose High quality. This produces output that matches the dimensions of a professionally printed document rather than auto-sized pages of varying dimensions.
- If the final PDF is too large for an email attachment, convert at Medium quality first. For most JPG photos, the difference in visible sharpness between High and Medium is negligible at normal reading size, but the file size reduction can be 40 to 60 percent. If that is still too large, run the output through the Compress PDF tool for an additional size reduction pass.
- Sort images by name before converting if your files are named with sequential numbers (receipt_01.jpg, receipt_02.jpg, etc.). The Sort by Name button orders them correctly in one click rather than requiring manual reordering when adding more than ten files.
Add your images, set the page size and quality, check the order, and download the PDF in seconds. If you need to convert a PDF back to individual image files, the PDF to JPG tool reverses the process in the same browser-based workflow.
