When is JPG better than ODD?
JPG photos are very detailed and supported by almost all browsers and devices, while ODD images are less detailed and support limited color profiles. As a result, JPG files are the best option for web images and photographs, given that they balance smaller file sizes and image quality.
JPG photos are widely supported, smaller, and load faster on websites, making them easier to share and transfer online as they consume fewer bytes and necessitate less storage space.
When is ODD better than JPG?
ODD images are vector graphics free, scalable, lossless, and branded file formats, while JPG is a raster graphics file format using lossy compression to delete specific image data. ODD is ideal for web-based and detached office applications and suites, including PowerPoint, Word Processors, and Spreadsheets.
The benefits of ODD images include being scalable without losing quality, easy conversion to other file formats, like Word and PDF, and cost-effective as they are free or open-source. They are also universally compatible and supported by older and new web browsers, platforms, software, and Operating Systems.

Differences and similarities between JPG and ODD images
JPG and ODD are two different file formats but similar in browser support. While ODD is vector-based while JPG is raster-based, they significantly differ in structure, file size, image quality, transparency and animation support, storage, performance, and compression methods.
Transparency
ODD supports transparency, while JPG does not. JPG hardly allows users to integrate transparent backgrounds in images. Besides, non-rectangular graphics and logos filled with many texts cannot work well in JPG file format.
In contrast, the ODD supports transparency because its file's texts and structure assume the XML format with the specified color scheme, which makes them viewable without special tools. Further, it uses its ability to encrypt lossless files with an alpha channel to make ODD file information transparent.
File Size
ODD files are comparatively larger than JPG files. Each ODD and sub-document has a maximum file dimension of 128x128 pixels, smaller than a comparable JPG file. On the other hand, the file size limit of a JPG file extension is 65,535 x 65,535 pixels, which equals to 4-gigapixels.
While an uncompressed ODD file appears smaller than an identical JPG file, judging by its file extension components, the compression type dictates the final file size. ODD uses lossless compression, while JPG supports lossy compression.
The ODD comprises multiple losslessly compressed images with varying color depths and sizes. Since lossless compression preserves all image details, it results in larger files than the lossy compressed JPG files. JPG loses image data during the lossy compression process, making them smaller than ODD files.
Image Quality
ODD and JPG are high-quality file formats. Both file formats support 8-bit depths each for RGB values, totaling 24-bit color. The file formats can record 256 (28) levels of RGB, resulting in 16 million colors. However, ODD files support a Wide Color Range, which is not in JPG.
However, the quality differences are seen in the compression method and scalability. ODD allows upward or downward scaling while maintaining image quality and resolution levels. In contrast, scaling a JPG image up or down causes it to lose quality, resulting in blurry or indistinct images.
Moreover, ODD retains its quality standard with its ZIP lossless compression, while JPG's lossy compression deletes image information, resulting in quality degradation compared to ODD images. Thus, ODD’s lossless compression and scalability justify high-quality standing over JPG.
Performance
ODD files are relatively larger than JPG files. The lossless and vector-based ODD files can sometimes hold multiple documents and sub-documents of different sizes than raster-based JPG files, making them larger than JPG.
As such, smaller JPG files consume fewer bytes and necessitate less bandwidth to be shared online, leading to faster loading times and increased user experience than ODD files. In contrast, multiple ODD files could be heavier and load slowly online, resulting in minimal user experience and less optimized search engines.
Structure
JPG is raster-based, while ODD is vector-based, making comparing the two file formats tricky. An ODD file stores drawing data and graphics in a standardized XML-based format. It assumes two structures: many sub-documents and a single XML document.
In contrast, a JPG file has a series of segments beginning with a marker with several binary OxFFXX data. The first marker has a binary value, 'OxFFD8', and ends with a binary value, 'OxFFD9'. The makers designate the time of the JPG data or information.
Animation
ODD file format supports animation or animated images, while JPG does not. Unlike JPG, ODD supports animations and scenes, rendering 3D objects through specific lighting and projection. The primary ODD graphical markup for drawings is on the drawing page, which has frames, forms, drawing objects, and layers. Thus, the drawing page elements in the presentation slides include animations and associated texts.
Storage
JPG files store smaller, lossy compressed data. Their smaller files consume fewer bytes, necessitate less bandwidth, and require less storage space. In contrast, the compressed ODD files are larger than the JPG files. Hence, ODD files consume more bytes and need more storage and bandwidth for file sharing.
Files and images in both formats can be stored indefinitely in a File System, Cloud, Content Delivery Network, Hard Drive, or Base64 encoding. The storage period is subject to the handling process, storage mediums used, and conditions.
Compression
The ODD uses ZIP lossless compression. Its archive has many files and directories with binary contents, necessitating a step-wise process. A password-protected ODD file retains its bundle structure while the XML file contents in the package are encrypted and compressed using the DEFLATE algorithm.
The lossless ODD images are smaller and of higher quality but larger than the lossy JPG images. JPG’s lossy compression method assumes block-based compression. The subsampling color information reduces the original file data through re-order, Huffman Coding, and DCT coefficients.
Thus, the JPG lossy compression technique is more efficient than ODD lossless compression. The JPG lossy format deletes specific image data, resulting in visible artifacts, particularly at high compression ratios. However, it allows users to control the data quality lost to attain the desired size.
Browser Support
ODD and JPG are widely supported across different platforms and browsers. Opera, Chrome, Safari, Firefox, Discord, Edge, Brave, and Internet Explorer widely support both formats. ODD is ranked the second most popular XML-based open standard file format on the web.
While no browser is reported to be incompatible with ODD files, JPG is incompatible or unsupported by Internet Explorer 6. This gives the ODD file format an edge over the JPG format regarding browser support.
Convert JPG to ODD or ODD to JPG
Use the most effective tool, convertjack, to convert JPG to ODD. ODD files are mostly preferred by users because they are widely supported and compatible with most web browsers and operating systems, are open-source (cost-effective), and are easily scalable to fit any screen size.
In contrast, convertjack is a well-known ODD to JPG converter. It helps generate smaller, detailed, and web-efficient JPG files widely supported across web browsers and platforms, resulting in increased user experience and easy file sharing.
