Images to PDF

Gather the exact JPG and PNG files that belong in the document. Remove duplicates, temporary crops, screenshots of editor controls, and any page that should not be shared. Open each source at full size and check focus, orientation, color, and readable text. A PDF can package the images, but it cannot recover detail missing from a blurred photo or a low-resolution screenshot. Keep the source files until the downloaded PDF has passed review.

Use clear filenames while preparing the set, especially for photographed forms, receipts, whiteboards, or handwritten notes. Names help with review before upload, but the order shown in the workbench controls the final page sequence. JPG suits photographs and scanned paper with continuous tones. PNG suits screenshots, diagrams, flat colors, and transparency. This tool accepts both formats in one job, so there is no need to convert every source to a common image type first.

Choose between one and 50 images with no more than 50 MB of combined input. Multiple selection, drag and drop, and pasted image files use the same file list. The workbench checks the extension, browser-reported type when useful, and actual file signature. A renamed WebP, PDF, or text file is rejected even if its filename ends in .jpg or .png. This protects the PDF builder from receiving a format it was not designed to decode.

Large phone photos can consume substantial browser memory after decoding, even when their stored files appear modest. If a job approaches the limit or the device has little free memory, resize copies before selection or divide the work into smaller PDFs and merge them afterward. Do not repeatedly submit a damaged image. Re-export it from a trusted image editor, then confirm that another viewer can open the new copy before returning to the workbench.

Each selected image becomes one PDF page. The first item in the list becomes page one, the second becomes page two, and the pattern continues to the end. Use the up and down buttons to move an item one position at a time. Remove a file if it does not belong. Adding another file appends it to the current list, so review the complete sequence after every addition rather than assuming the file picker supplied the intended sort order.

For a photographed document, check page numbers, front and back sides, attachments, and blank separators. For receipts or project evidence, choose a sequence that another person can understand without the original folder. If a page belongs in two positions, add a second copy intentionally. The builder does not infer chronology from capture dates or filenames. The visible order is the only page-order instruction applied to the result.

Match each image creates a page around the image's native pixel dimensions plus the selected margin. It avoids forcing sources with different shapes onto one paper standard. This option works well for screen captures, artwork, references, and digital review where exact print dimensions are not required. The page can still appear at a different zoom in a PDF reader because viewers choose their own display scale.

A4 and US Letter create consistent paper-sized pages measured in PDF points. Use the standard expected by the recipient, printer, filing system, or submission portal. A4 is common internationally, while US Letter is common in the United States and some related workflows. A paper choice does not assign a physical DPI value to the source. It determines the page box, then the image is placed inside that box using the selected fit and margin.

Orientation is available when A4 or US Letter is selected. Portrait makes the page taller than it is wide. Landscape swaps those dimensions. Choose based on the document's intended reading direction, not only the orientation stored in the first source. A set of wide presentation captures often fits landscape better, while photographed letters and forms usually fit portrait. The same orientation applies to every page in the generated PDF.

A mixed set can contain both tall and wide images. One shared paper orientation keeps the document consistent but may leave larger empty bands around some pages. If each source must use a different paper orientation, create separate PDFs for the groups and combine them with Organize PDF. Automatic page size is another option when consistent paper boxes are less important than retaining each source shape.

Contain keeps the complete image visible. It scales down a large source when needed, centers it, and leaves unused page area around shapes that do not match the paper. Small images are not enlarged in contain mode, which avoids inventing pixels and making defects more obvious. Use contain for forms, screenshots, diagrams, identity documents, and any source where text or detail near an edge must remain visible.

Cover fills the available page area and center crops any overflow. It can produce a full-page photographic result, but it may remove content at the top, bottom, or sides. The crop position is centered and cannot be adjusted per image. Check every source against the chosen page shape before using cover. Prepare manual crops first when faces, signatures, totals, labels, or other important details sit close to an edge.

Margin controls the clear area around each image and accepts values from 0 to 100 points. Seventy-two points equal one inch in PDF coordinates. A zero margin lets the image reach the page boundary in the PDF, although many printers still have a non-printable hardware edge. A moderate margin can make photographed pages easier to read and leaves room for binding, notes, or printer variation.

The same margin is applied on all four sides and on every page. Large margins reduce the area available to the image. In contain mode, that can make text smaller. In cover mode, it changes the crop required to fill the remaining rectangle. Test the output at normal reading size and with the intended printer settings. Do not rely on a browser preview alone when a filing office or print shop has exact margin requirements.

The selected image bytes stay in the current browser tab. The tool loads PDF code only after Create PDF is selected, embeds each validated JPG or PNG into a new document, adds pages in the displayed order, and saves a separate PDF download. No PWRKIT conversion worker receives the images. The application does not place image contents, filenames, or generated PDF bytes in analytics events.

Local processing reduces transfer exposure, but it does not remove every privacy concern. The source files already exist on the device, and the download can enter browser history, synchronized folders, backups, endpoint monitoring, or shared storage. Use an approved device and destination for confidential records. Close the tab after saving and reviewing the result when workplace handling rules require it. Browser memory is released by the browser, not by a remote deletion promise.

JPG bytes are embedded as JPG, and PNG bytes are embedded as PNG. The builder does not apply another lossy photo compression pass. That preserves the available source detail, but it also means the PDF can be close to the combined image size plus document overhead. Page placement changes how an image is displayed without creating a higher-quality source. Enlarging a small image in cover mode can make pixels, compression blocks, or soft text easier to see.

If the result is too large, optimize copies of the images before creating the PDF or use Compress PDF after download and compare quality carefully. Reducing pixel dimensions often saves more space than changing page margins. Keep an uncompressed source set when the document may need future edits. Compression choices depend on whether the PDF is for screen review, email, archive, optical character recognition, or high-quality printing.

Text visible inside an image remains pixels. Creating the PDF does not add selectable text, reading order, document headings, language metadata, alternative text, or form fields. Search, copy, screen reader access, and text extraction will not work as they would in a tagged source document. If the images represent scanned pages, an OCR step is needed to create a text layer, followed by human review for names, numbers, punctuation, and reading order.

A successful OCR result still does not guarantee an accessible PDF. Tables, columns, diagrams, signatures, and handwritten notes need appropriate structure and descriptions. For official publication, use an accessibility workflow that can tag the document, set its language and title, define reading order, and validate it with the expected assistive tools. This image packaging tool does not claim to perform those tasks.

Open the download in a separate PDF reader. Confirm the page count, order, paper size, orientation, margins, edge cropping, image sharpness, color, and file size. Zoom into small text and inspect the first and last page. If the document came from photographs, check shadows, glare, skew, clipped corners, and repeated pages. Compare the result with the visible source list instead of trusting memory.

Then test the real delivery path. An email service, upload portal, printer, records system, or document-signing product may impose its own page, size, encryption, or PDF-version rules. A file that opens locally can still be rejected by the final system. Keep the source images and selected settings until acceptance is confirmed. The tool creates a new file and never changes the originals.

If selection fails, verify that the file is a real JPG or PNG and within the combined limit. Open it in a trusted image viewer, then export a fresh copy if it is damaged. If browser memory becomes tight, reduce source dimensions or create smaller groups. If a page is in the wrong position, use the order controls and rebuild the PDF. Renaming the downloaded file cannot change the internal page sequence.

If edges disappear, switch from cover to contain or prepare a better crop. If pages are inconsistent, choose A4 or US Letter instead of automatic sizing. If small sources look soft, avoid enlargement and obtain higher-resolution originals. If the output is too large, optimize source copies before another build. When the PDF requires OCR, encryption, certified signatures, or formal accessibility tags, continue in a tool designed and reviewed for that specific requirement.
