Image Format Converter
Convert between JPG, PNG, and WEBP — correctly, in your browser.
Also known as: Image converter, Photo format converter, WEBP to JPG converter
How it works
- 1Upload one or more images — JPG, PNG, WEBP, GIF, BMP, and most other formats work as input.
- 2Choose the format you want to convert to: JPEG, PNG, or WEBP.
- 3Adjust the quality slider if you picked a lossy format (JPEG or WEBP).
- 4Click Convert — a single image downloads directly, and multiple images download together as a ZIP.
Why use Image Format Converter
Converts to the 3 formats that matter most
JPEG, PNG, and WEBP cover the vast majority of everyday format-conversion needs.
Quality control where it applies
Adjustable quality for lossy targets (JPEG, WEBP); PNG always stays fully lossless.
Honest about GIF animation
Flags upfront that animated GIFs convert using only their first frame, instead of quietly producing a broken result.
Batch conversion
Convert a whole folder of mixed-format images to one consistent format at once.
Wide input support
Accepts JPG, PNG, WEBP, GIF, BMP, and most other formats your browser can open.
Nothing uploaded
Every image is decoded and re-encoded locally in your browser tab.
Who uses Image Format Converter
Opening a WEBP in older software
Convert a WEBP image to JPEG or PNG so it opens in software that doesn't recognize WEBP.
Shrinking a PNG screenshot
Convert a large PNG screenshot to JPEG or WEBP when a smaller file matters more than pixel-perfect losslessness.
Standardizing a mixed-format folder
Convert a folder containing a mix of JPG, PNG, and WEBP files to one consistent format.
Meeting a platform's format requirement
Convert an image to whichever format a specific upload form or platform actually requires.
Extracting a still from an animated GIF
Convert an animated GIF to a static JPEG or PNG when you just need a single frame as an image.
Preparing images for older browsers
Convert modern WEBP assets back to universally-supported JPEG or PNG.
About Image Format Converter
Format conversion comes up constantly: a WEBP image that a tool or older software refuses to open, a PNG screenshot that's larger than it needs to be as a JPEG, or a photo you want in WEBP because it's smaller for the same visual quality. This tool converts between the three formats modern browsers can both decode and re-encode reliably — JPEG, PNG, and WEBP — using the same rendering engine your browser already uses to display images on any web page.
Each target format is handled according to what it actually supports. JPEG and WEBP are lossy and get a quality slider, since that's the real trade-off you're making — smaller file versus more compression artifacts. PNG is lossless, so there's no quality setting to adjust; converting to PNG always preserves full image detail, at the cost of a larger file for photographic content.
One honest limitation worth stating plainly: this tool accepts animated GIFs as input, but the output is always a single static frame. Browsers don't expose a way to decode a GIF's individual animation frames through the image APIs this tool uses, so there's no way to carry the animation through a format conversion here — and rather than silently produce a broken or misleading result, the tool tells you upfront when an animated GIF is detected.
Batch conversion applies the same target format and quality setting across every image you add, then bundles the results into a ZIP file if you converted more than one — useful for standardizing an entire folder of mixed-format images to one consistent format in a single action.

| Installation | None | Required | None |
| File privacy | Never leaves your device | Stays local | Uploaded to a server |
| GIF animation honesty | Flags the first-frame-only limitation upfront | Varies by app | Often unclear or silently broken |
| Speed | Instant, on-device | Fast | Depends on upload + server queue |
| Watermarks | Never | Never | Sometimes on free tiers |
Pro tips
- Converting to PNG always preserves full image quality — use it when you need a lossless result, not when you need a small file.
- WEBP at 80-90% quality is usually smaller than an equivalent-quality JPEG, making it a good default for photos when compatibility isn't a concern.
- If your source is an animated GIF, expect only the first frame to carry over — there's no way around this using in-browser image decoding.
- Batch conversion applies one format and quality setting to every image — for very different source images, converting in smaller batches gives you more control.
- Converting a JPEG to PNG and back to JPEG doesn't recover lost detail — each lossy re-encode compounds, so keep an original copy when quality matters.

Privacy & security
Format conversion is a small, routine task — it shouldn't require handing your images over to an unfamiliar server just to change their file extension.
Each image is decoded and re-encoded locally — never uploaded, never seen by a server.
No account, no email, no login — just images in, converted images out.
Nothing is retained after your download finishes; there's no copy waiting on a remote server.
Equally private whether you're converting a single photo or a batch of hundreds.
Frequently asked questions
Is my image uploaded to a server?
No. Every image is decoded and re-encoded entirely in your browser — nothing is ever uploaded.
Can I convert an animated GIF and keep the animation?
No — the output is always a single static frame. Browsers don't provide frame-by-frame GIF decoding through the image APIs this tool relies on.
Does converting change the image dimensions?
No, only the file format and, for lossy formats, the compression quality. Use Image Resizer separately if you also want to change dimensions.
Which format should I pick for a photo I want to share?
WEBP usually gives the smallest file for a given visual quality; JPEG is the safer choice for maximum compatibility with older software.
Can I convert multiple images at once?
Yes. Add as many images as you like and convert them all to the same target format in one action — you'll get a ZIP file if you converted more than one.
Is there a limit on image size or count?
No hard limit — very large images or batches just take a little longer since everything processes on your device.
Troubleshooting
My animated GIF lost its animation after converting
This is expected — browsers don't expose a way to decode individual GIF animation frames through the APIs this tool uses, so conversion always uses just the first frame. There's currently no in-browser workaround for this.
The converted PNG is larger than my original JPEG
This is normal. PNG is lossless, so converting a photographic JPEG to PNG usually increases file size since there's no compression trade-off being made anymore.
The quality slider is missing
It only appears for lossy target formats (JPEG and WEBP) — PNG has no quality setting because it's always fully lossless.
One of my images won't convert
The file may be corrupted or in a format your browser can't decode. Try opening it in an image viewer first to confirm it's valid.
