Add your AVIF file
Drop one or more .avif files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting a .avif image to .jpg re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting a .avif image to .jpg re-encodes the pixels for a different balance of size, quality, and support. An .avif file stores a still image (or sequence) coded with the AV1 video codec inside a HEIF-derived container. It is currently among the most efficient image formats deployed on the web, routinely beating JPEG by half at similar quality while adding HDR, wide gamut, and alpha.
A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos. For this route the practical draw is opens everywhere, from 1990s software to the newest phone and excellent size-to-quality ratio for photographic content — balanced against every re-save re-compresses the image, so quality erodes across editing generations, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .avif, encoding is much slower than JPEG or WebP, especially at high effort settings. Switching to .jpg buys you opens everywhere, from 1990s software to the newest phone, which is why it is the better fit for publishing photographs on websites where file size and universal support matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | AVIF image (.avif) | JPEG image (.jpg) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | encodes AV1 intra frames; both lossy and a mathematically lossless mode are defined | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded |
| Strongest at | serving hero images and photo galleries where bandwidth savings are significant | publishing photographs on websites where file size and universal support matter |
| Weak spot | encoding is much slower than JPEG or WebP, especially at high effort settings | every re-save re-compresses the image, so quality erodes across editing generations |
| Metadata | eXIF and XMP are stored as metadata items in the HEIF container alongside ICC profiles or CICP color signaling, and mainstream encoders preserve them on conversion | carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails |

Select .jpg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if JPG is selectable, the route is real and validated.
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid JPG file. Outputs keep the original filename with the .jpg extension.
A second lossy step always costs a little, because avif is lossy-oriented and jpg is lossy-oriented and each encoder discards detail differently (generation loss). At the default quality the difference is rarely visible; avoid repeated round-trips between .avif and .jpg.
Yes — the .avif file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
JPEG is supported by every mainstream operating system, browser, image editor, and printer driver in use today. It decodes natively on iOS, Android, Windows, macOS, and Linux without any add-on codecs, and every browser has rendered it since the format reached the web in the 1990s.
It depends on the content: compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded. Convert one representative file first and compare before batch-processing a large set.
In .avif, eXIF and XMP are stored as metadata items in the HEIF container alongside ICC profiles or CICP color signaling, and mainstream encoders preserve them on conversion. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .avif → .jpg → .avif is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
