Image to JPG converter — free and private
Convert a supported image to JPG — or up to 50 at once — without uploading it. Choose your files, optionally set a size limit, and download standard .jpg images with their original oriented dimensions, one by one or together in a ZIP.
No sign-up, no watermark. Size targets are best-effort; the final file size is always shown.

Up to 50 images at once, 80 MB each.

Supported sizes and formats
Transparent areas become white. Animated images use the first frame. TIFF pages have individual downloads and a ZIP. JPG re-encoding is lossy; embedded metadata is removed unless you keep photo details (EXIF), which are then written upright, without the embedded thumbnail.
Up to 80 MB per input, 40 megapixels and 10,000 pixels per side for each image. TIFF: up to 50 pages, 120 megapixels combined. Outputs may total up to 128 MB. Files beyond these limits are rejected, not resized. SVG, PSD and camera RAW are not supported. Some codec variants may not decode in your browser.
If a size limit cannot be met, the actual file size is shown and original dimensions are preserved.
How do I convert an image to JPG?
Choose a supported image and select Convert to JPG. Leave the size field empty to keep high quality and original pixel dimensions. Download the result after conversion finishes. No account, watermark or upload is required.
The converter accepts JPEG, PNG, WebP, HEIC, HEIF, AVIF, BMP, GIF and TIFF. HEIC and TIFF decoders load only when needed. Other formats depend on the image support available in your browser; uncommon codec variants may still fail to decode.
How it works
- Choose one image or manySelect up to 50 supported images from your device — iPhone HEIC photos, PNG screenshots, WebP downloads. The tool reads them locally, one after another. A multipage TIFF is treated as one input with multiple output images.
- Choose an optional size limitLeave the KB field empty for the default high-quality result. If an upload form has a size ceiling, enter it here. Quality can be reduced to approach the target, but pixel dimensions stay unchanged.
- Download your JPGEach finished result shows its dimensions and actual size; an image that cannot be converted is listed with the reason and the others go on. Download images separately or use Download all as ZIP to save the complete set.
What changes when converting to JPG?
JPG is a lossy format for still images. The converter re-encodes the picture, keeps its orientation and full frame, and removes embedded metadata — unless you tick Keep photo details (EXIF): then the camera, the date taken and the location stay in the JPG, written upright and without the embedded thumbnail. It does not sharpen missing detail or apply document-scanning filters.
Transparent areas become white because JPG cannot preserve transparency. Animated GIF, WebP or AVIF images become a static first frame; the animation is not included. Choose a format that supports transparency or animation if you need to retain those properties.
Large images and TIFF documents
Inputs can be up to 80 MB. Each decoded image can contain up to 40 megapixels with no side above 10,000 pixels. TIFF files can contain up to 50 pages and 120 megapixels combined. One input’s converted output is limited to 128 MB, and a batch stops at 256 MB of JPGs and says how far it got.
Images beyond these limits are rejected with a message rather than silently resized or truncated. Very large files can still exceed the memory available in your browser. Try a smaller source if your device cannot finish decoding it.
SVG, PSD and camera RAW files are not supported. This is a common-image converter, not a promise to decode every image format. For a JPEG extension requirement, the dedicated JPEG to JPG page provides the same conversion workflow.
Frequently asked questions
Does this convert PNG and HEIC to JPG?
Yes. PNG, HEIC and the other listed raster formats use the same local conversion workflow. Supported codec variants and available browser memory determine whether a particular file can be decoded.
Will the output keep the original dimensions?
Yes, within the displayed processing limits. The default does not shrink the image. An optional KB limit adjusts JPEG quality only and reports when the target cannot be met.
Can I convert many images or all TIFF pages at once?
Yes. Choose up to 50 images in one go; each converted JPG has its own download and Download all as ZIP saves the set. A multipage TIFF produces one JPG per page in the same list. Files above the stated page or memory limits are rejected.
Are my pictures uploaded?
No. Decoding, conversion and ZIP creation run in your browser. Images and filenames are not sent to LensUp.
