How to Convert Scanned JPEG with Text to Searchable PDF Document

JPEG is probably the most popular extension for storing and transferring images. Many users prefer this format for sending photographs by email or uploading them on social networks. The reasons are obvious: JPEG can be opened with even the most basic image viewer, provides small size and decent image quality.

The format is also used as output extension by many scanning and faxing devices. Using JPEG you can get a quick and small digital copy of a document. As this is a raster format, however, what you get is an image reproduction of the document. Not an actual text. This means scanned JPEG cannot be searched or edited. Depending on your area of work, this can be a considerable problem. For example, if you scan a certificate or an invoice that you need to make quick corrections to, the JPEG format will not be of much help.

How to Automatically Select Files According to their Size & Extension

reaConverter is one of the most powerful converter of image formats, supporting over 640 extensions. One of its main advantages is that it allows you to work with large groups of files at once, which is ideal for photographers, designers, webpage creators and other professional image handlers. But it can also work great for amateurs!

To avoid the hassle of selecting images one by one when you have to edit a large number of them, reaConverter now lets you select them automatically using file size and/or extension as criteria. The option is not only available on the software’s GUI interface, in the Advanced file select section, but it can also be operated via command-line interface.

How to Create a Linearized PDF

PDF (Portable Document Format) is one of the most widely used formats for storing and transferring both text and image data. Some of its main advantages include being compatible with any operating system, containing formatting that does not change from one viewer to another and offering great quality at accessible size.

PDF is widely used for uploading online content, and for this purpose in particular it can be optimized via linearization. This basically allows you to download pages as you read them. Or in other words, spend significantly less time between the moment you click on a link to a PDF file and the moment you actually get to read it.

How to Customize Precision during Vectorization

The automated conversion of a raster image made up of pixels into scalable vector graphics is a complicated process that often has mixed results. The accuracy of the output vector depends on several things, including the quality of the input raster, on how detailed or “cleaned up” of noise is the image, on conversion algorithms etc. Common problems are the incorrect shape and color rendering.

To prevent the issues that might come up during vectorization, reaConverter’s latest edition offers several ways to customize the raster-to-vector conversion process. Opting for an outline or centerline algorithm and ignoring raster data when the input vector includes mixed vector-raster content are among the available possibilities.

How to Convert Multipage DWF Files

DWF (Design Web Format) is an Autodesk extension usually attached to drawings representing architectural plans, building projects or product designs. The format was released in mid-1990s with the aim of improving accessibility for users who don’t necessarily know how to use AutoCAD but are part of creative teams responsible for designs.

DWF files allow you to view, review and print design data. They can be single-page or multipage and are highly compressed, which means they are usually small in size and easy to transfer or store. However, most regular image viewers cannot open DWF files. They usually require some specialized software or a CAD program.

How to Convert Scanned TIFF Images with Text to Searchable PDFs

Do you a have a printed document and need to make a digital copy of it? Scanning is a quick option. Or an even quicker one is photographing it with your smartphone. In both cases, what you will get is an image of the text, most likely saved under a raster format, such as PNG, JPEG or TIFF. In fact, the latter is often preferred by scanning and faxing devices due to its good quality rendering of text.

But while being an accessible and flexible format, supporting both lossy and lossless compression, TIFF has one major disadvantage. Texts scanned under this format cannot be edited or searched. This might be a problem if, for example, you have a scanned book and need to look for a certain keyword. Or if you want to translate the scanned document via machine translation. The best solution in such cases is converting to a format that can be edited and searched — PDF.

How to Convert 3D STL Files to 3D DXF

STL is an image format mainly used in a type 3D printing technology called stereolithography, involving the production of three-dimensional models, patterns and prototypes with polymers. The STL format was initially launched in the 1980s by 3D Systems, the first company to introduce and develop stereolithography, and it is nowadays supported by several computer-aided design (CAD) programs.

STL files store black-and-white 3D objects, including only geometry data and no color, texture or other attributes usually featured by images created with CAD software.

In comparison, AutoCAD’s native interchange format DXF tends to have more popularity and offer more complex object descriptions than STL. DXF supports both 2D and 3D object rendering, and its features can vary according to the AutoCAD release to which the format is associated.

Ignore Raster Data when Converting from Vector Formats

Vector files are sometimes complex layered image structures that can contain both vector and raster data. For example, you can have a detailed scalable map made up of lines and curves also including raster representations of some map elements, such as an aerial photograph or satellite image.

When converting PDF, EPS, CDR, XPS, SVG and other vector formats with mixed raster-vector content to raster formats such as JPEG or PNG, a fair representation of colors and quality will be ensured. But when you convert to another vector format, image quality might become an issue.

How to Rotate PLT Files During Conversion

If you are planning to print a graphics file on a plotting device, then converting it to PLT is the best option. Whether you are using a cutting plotter, a pen plotter or some other similar machine, the PLT format will ensure what you create on screen will match what you see in print.

PLTs are vector files that use the HPGL language and can be sent directly to print on a plotter. Such devices are often used for large-scale graphics such as maps, detailed plans or diagrams, posters and many more. The PLT format was originally created for Hewlett-Packard printers only, but in time became an actual standard in the industry. PLTs are currently compatible with most brands of plotting machines.

How to Create EPS Files with Preview

EPS (Encapsulated PostScript) is a vector format used for storing images and drawings. Such files can contain maps, logos or detailed layouts and can include both vector and bitmap data. Compared to the similar PS format, EPS not only uses the PostScript language to describe graphics, but also stores an “encapsulated” preview of low-resolution, that can be displayed by some programs.
