Images to Convert0 images
Balance JPG or WebP appearance against file size before downloading.
Decoding and conversion happen entirely in browser memory.
Choose the output format by transparency, compatibility, and reuse
Changing an extension is not the same as converting image data. A real conversion decodes the source and encodes a new file, which can remove transparency, change file size, and introduce loss depending on the destination format.
Step by step
- Inspect the source
Check whether the image contains transparency, fine interface text, photographic detail, animation, or metadata that must be retained elsewhere.
- Choose the receiving format
Select JPG for broad photo compatibility, PNG for lossless graphics and transparency, or WebP for compact modern web delivery.
- Set quality where relevant
JPG and WebP quality balance detail against file size. Start high, inspect the output, and lower it only as far as the destination allows.
- Verify the result
Open the converted file in the actual app or service, check transparent edges and colors, and retain the source for future conversions.
Decision guide
- JPG
- Best for photos and broad compatibility, but it has no alpha transparency and repeated conversion can accumulate artifacts.
- PNG
- Best for logos, screenshots, diagrams, and transparent pixels when lossless output matters more than size.
- WebP
- A strong default for modern websites when smaller delivery files and transparency may both be useful.
- Quality control
- Affects lossy JPG and WebP output. It does not make a low-resolution source sharper or repair previous compression.
Important limits
- Converting a transparent image to JPG fills transparent pixels with a solid background.
- Animated sources are handled as still images unless a tool explicitly supports animation.
- A converted file may lose EXIF or application-specific metadata even when the visible pixels look unchanged.
- Browser decoding support for camera formats such as HEIC depends on the current device.
04 · Common questions
Common questions
Why did the transparent background disappear?
JPG cannot store alpha transparency. Use PNG or WebP when transparent pixels are required.
Which format is smallest?
It depends on the image. WebP is often efficient for web delivery, JPG works well for photos, and PNG excels at lossless graphics.
Does conversion upload my image?
No. Decoding and re-encoding run in the current browser.
Convert SVG and other images to JPG, PNG, or WebP
Choose JPG for broad compatibility and photographic content, PNG for lossless graphics and transparency, or WebP for compact images in modern browsers and applications. Every output is newly encoded using the selected format.
SVG input is sanitized and rasterized locally before export. HEIC and HEIF support depends on whether your browser can decode the source image; supported files never need to be sent to a conversion server.
Image conversion questions
Which format should I choose?
Use JPG for photos and maximum compatibility, PNG when transparency or lossless graphics matter, and WebP when smaller web-ready files are the priority.
What happens to a transparent PNG converted to JPG?
JPG has no alpha channel. OmniKit fills transparent pixels with white before encoding the JPG file.
Does conversion preserve EXIF metadata?
No. The browser creates a new file from decoded pixels, so common EXIF location, camera, and capture information is not copied.
