Questions
Quick answers about this PurePDF workflow.
Is the image converter free?
Yes. Converting images between formats is completely free — no signup, no watermarks, no daily limits.
Do my images get uploaded to a server?
Yes for this tool. Images are converted on our servers over encrypted HTTPS and automatically deleted within minutes.
What formats can I convert between?
JPG, PNG, WebP, AVIF, GIF, SVG, HEIC/HEIF, TIFF, BMP, and PDF — over 90 conversion pairs.
Can I convert multiple images at once?
Yes. Batch upload is supported — convert dozens of images in one run and download them together.
Can I control the output quality?
Yes. Adjust the quality level for lossy formats like JPG, WebP, and AVIF to balance size and sharpness.
Which format should I choose for my website?
WebP or AVIF give the smallest files for web use. Use JPG for maximum compatibility and PNG when you need transparency.
How to convert images between JPG, PNG, WebP, HEIC, and more
One converter for every common image format
Image formats multiply quickly. iPhones save HEIC, websites want WebP or AVIF, older software only opens JPG or BMP, and designers hand over PNG or SVG. PurePDF’s image converter handles JPG, PNG, WebP, AVIF, GIF, SVG, HEIC/HEIF, TIFF, BMP, and PDF, covering more than 90 conversion pairs from a single page.
You can upload a batch of images, convert them in one run, and download them together, which saves repeating the same conversion file by file.
Which format should you choose?
The right output depends on where the image is going:
- JPG: the safest choice for photos when compatibility matters most, such as email and older apps.
- PNG: lossless, with transparency, for logos, screenshots, and graphics with sharp edges.
- WebP and AVIF: the smallest files for websites, usually far smaller than JPG at similar quality.
- HEIC: space-efficient photos from Apple devices; convert to JPG when a device or site will not open them.
- PDF: for bundling images into a document you can print or attach.
Controlling quality and file size
Lossy formats such as JPG, WebP, and AVIF let you adjust a quality level. Lower quality produces smaller files; higher quality keeps more detail. For web images, a moderate setting usually looks identical to the original at a fraction of the size. Converting a lossy image to a lossless format such as PNG will not restore detail that was already discarded, so keep originals where you can.
How your images are processed
Image conversion happens on PurePDF servers, not in your browser, because several formats (HEIC and AVIF among them) cannot be encoded reliably in every browser. Images are uploaded over encrypted HTTPS, converted, and automatically deleted within minutes. There is no signup, no watermark, and no daily limit.
Dedicated pages for common conversions
Every conversion pair also has its own page, such as HEIC to JPG, PNG to WebP, or WebP to JPG, with notes on what changes between the two formats. If you mainly need smaller files rather than a different format, Compress Image reduces size while keeping the format you already have.
