Why use Aback Images for jpg to pdf
Where the PDF goes next
PDF opens in every browser, operating system and office suite.
PDF next to JPG
Both formats are lossy, so the size mostly follows the quality setting; at the default the PDF usually lands in the same range as the JPG.
A second lossy pass
JPG is lossy already, since it stores lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution, so keep the quality at or above the default to avoid stacking a new layer of artefacts on the old one.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
JPG vs PDF
What changes from JPG to PDF
Encoding: the JPG uses lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution; PDF uses per object: images inside are usually JPEG or Flate-compressed, and the download is a one-page PDF with the image embedded as a JPEG.
Bit depth: 8 bits per channel in the JPG; PDF allows whatever the embedded images use, and the PDF written here has 8 bits per channel.
Colour: YCbCr shown as RGB, greyscale, or CMYK from print software in the JPG; PDF supports RGB, CMYK, greyscale or spot colours, written here as 8-bit sRGB.
Metadata: the JPG can carry EXIF (camera, date, GPS), XMP, IPTC and an ICC profile in APP segments; PDF can carry document info and XMP, but nothing is copied across.
About JPG
JPEG is the universal photo format. It compresses by discarding fine detail the eye is least sensitive to, which makes photos small but blurs sharp edges and text if pushed too far.
A JPEG starts with the bytes FF D8 and is a run of marker segments: APP1 carries EXIF and often a thumbnail, APP2 an ICC profile, DQT the quantization tables that decide the quality, and SOS the compressed scan, which ends at FF D9.
JPG files usually come from cameras, phones, scanners and almost every app that saves photos.
About PDF
PDF is the standard for documents that look identical everywhere. Images placed in a PDF can be printed, emailed and combined into multi-page documents.
When converting JPG to PDF makes sense
PDF is the better choice for sharing, printing and submitting documents, while JPG suits photographs that need to open anywhere.
PDF strengths: Opens identically on every device; Multiple pages in one file; Print-ready page sizes. Drawbacks to weigh: Not an image format: harder to edit or embed.
Limitations
- A JPEG that has been edited and re-saved several times has already lost detail; convert from the camera original when you have it.
- The page matches the image size unless you choose a paper size, and the image is embedded as a JPEG.
- To put several images into one multi-page PDF, use Image to PDF.

Frequently asked questions
Does converting JPG to PDF lose quality?
PDF is lossy, so detail the eye barely notices is discarded to save space. The JPG was lossy already, so keep the quality high to avoid stacking artefacts.
Can I put several images in one PDF?
This converter creates one PDF per image. To combine many images into one multi-page PDF with page size and margins, use Image to PDF.
Which apps open PDF files?
Every browser, operating system and office suite.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
