JPG to PDF and PDF to JPG — Convert Images Without Uploading

Combine images into a PDF, or split a PDF back into individual images — either direction, entirely on-device.

Images ↔ PDF Converter reads whatever you drop and picks its own direction: image files switch it into combine-into-a-PDF mode, a single PDF switches it into split-into-images mode. Each direction sizes its output correctly for what you actually gave it — an output PDF page matches its source image's own aspect ratio rather than being stretched onto a fixed Letter or A4 sheet, and a PDF split into images renders each page at whichever resolution you choose.

How to convert JPG to PDF

1. Drop one or more JPG, PNG, WebP, GIF or BMP files onto the upload zone, or click it and select several images at once.
2. Drag the thumbnails into the page order you want, and press the rotate button on any photo that arrived sideways.
3. Pick a page resolution of 72, 150, 300 or 600 DPI; it decides how large each page measures, while JPEG and PNG pixels are embedded unchanged.
4. Convert and download one PDF holding a page per image, each page shaped like the picture on it.

How to convert PDF to JPG

1. Drop a single PDF; the tool switches itself into PDF-to-images mode.
2. Change the format from the default PNG to JPEG for smaller files, and set the JPEG quality slider anywhere from 40% to 100%.
3. Choose 72, 150, 300 or 600 DPI; 150 is the default, and higher settings give sharper but heavier images.
4. Convert, then save pages one at a time or grab every page together with Download all as ZIP.

One drop zone, two independent tools underneath

The mode switch isn't a setting you pick; it's inferred from the file type you drop, and each direction runs its own worker with its own settings and its own results, completely separate from the other. Dropping images after already converting a PDF to images doesn't mix the two — each direction's state only ever reflects what you've fed it in that direction.

Why a combined PDF's pages aren't all the same size

Combining images into a PDF sizes every output page to that specific image's own pixel dimensions divided by your chosen DPI, converted into PDF points. A tall portrait photo and a wide landscape screenshot dropped into the same batch each get a page shaped like themselves, not squeezed or padded to match a fixed paper size — the same choice most dedicated images-to-PDF tools make, and the one a generic office-suite print-to-PDF usually gets wrong.

Which image formats keep full quality

JPEG and PNG embed directly, byte-for-byte, with no decode-and-re-encode step and therefore no generation loss at all. Anything else you drop — WebP is the common case, with GIF and BMP handled the same way — has to be decoded to raw pixels and re-encoded to PNG first, a real quality and file-size trade-off, but one only paid for formats that actually need it, not for every image regardless of type.

Splitting a PDF back into images

Going the other direction, each page renders at whichever of four resolutions you pick — 72, 150, 300, or 600 DPI — as either lossless PNG or JPEG with an adjustable quality slider. Multi-page exports number their filenames with enough leading zeros that a hundred-plus-page document still sorts correctly in a plain folder view, and a single download-all button bundles every page into one ZIP instead of triggering a hundred separate downloads.

You can build a PDF from up to 40 images per batch for free, as many batches as you like, and Pro removes the per-batch number. Splitting a PDF into images has no page limit on either plan.

What this tool doesn't preserve

• Splitting a PDF into images always rasterizes the page, even one that was mostly vector graphics or selectable text — the resulting image has no text layer at all, which matters if you need the content searchable afterward rather than just viewable.
• Combining images into a PDF doesn't run any OCR or add a text layer of its own; a PDF built this way is a visual document, not a searchable one, unless you run it through PDF OCR Reader afterward.
• Photos embedded inside a PDF aren't pulled out as their original files; the split direction renders whole pages, so an embedded picture comes back as part of its page image.
• There's no fixed paper size or margin option for combined PDFs, so pages follow each image's proportions rather than a uniform A4 or Letter sheet.

Questions people ask about Images ↔ PDF Converter

Can I combine multiple JPGs into one PDF?

Yes. Select or drop all the JPGs together and each one becomes a page of the same PDF, in the order you arrange the thumbnails. The free tier takes 40 images per batch; for more, run several batches and join the resulting files with PDF Merge.

Will converting reduce my image quality?

Going from JPG or PNG to PDF loses nothing, because those files are embedded byte for byte; WebP, GIF and BMP are converted to lossless PNG first. Going from PDF to images, sharpness depends on the DPI you choose, and a low JPEG quality setting adds compression artefacts that PNG output avoids.

Can I convert iPhone HEIC photos to PDF?

Not directly. The file picker accepts PNG, JPEG, WebP, GIF and BMP, and the tool bundles no HEIC decoder. Export or convert the photos to JPEG first, then combine them here, where those JPEGs will be embedded without any re-encoding.

Can I set A4 or Letter page size and margins?

No. Every page takes the shape of its image at the chosen DPI, with no margins added, so pictures are never stretched or padded. To get A4 pages anyway, size each image to 2480 × 3508 pixels before converting and pick 300 DPI here; each page then comes out at A4 dimensions.

Can I convert PDF to PNG instead of JPG?

Yes, and PNG is in fact the default output when you split a PDF. It's lossless, so text edges and line art stay crisp, but the files are larger than JPEG; switch the format to JPEG when a smaller download matters more than perfect detail.

Why did my images-to-PDF file come out with oddly-sized pages?

Each page is sized to exactly match its source image's own pixel dimensions at your chosen DPI, so a mix of portrait and landscape images produces pages with different shapes rather than every page forced onto one fixed paper size.

Can I still select text after splitting a PDF into images?

No — splitting always rasterizes each page into a plain image, with no text layer carried over, so any text that was selectable in the source PDF becomes part of the picture rather than remaining searchable or copyable.

Is there a limit on how many pages or images I can convert?

Combining images into a PDF is capped at 40 images per batch on the free tier, with no limit on how many batches you run; Pro removes that cap. Splitting a PDF into images has no page limit on either plan, and neither direction has a file-size cap.
