EPS to JFIF Converter

EPS to JFIF: Rasterising PostScript Into a JPEG

An EPS is Encapsulated PostScript — a self-contained PostScript program with a %%BoundingBox comment declaring how much space the artwork occupies, measured in points at 72 to the inch. It might be pure vector geometry, or it might be a raster image with a PostScript wrapper around it; the extension does not tell you which. A .jfif is a JPEG. The JPEG File Interchange Format was published as JFIF 1.02 in 1992 and formalised two decades later as ITU-T Recommendation T.871 (May 2011), also issued as ISO/IEC 10918-5.

So this conversion has one job: run the PostScript, capture the resulting pixels, and JPEG-compress them. The interesting question is not whether it works but at what size, because an EPS has no pixels of its own — it has a coordinate system. The answer, measured below, governs everything else on this page.

EPS and JFIF Side by Side

A .jfif file from this converter is an ordinary JPEG datastream — the extension is the only thing that separates it from a .jpg. It exists because a number of intake portals, older Windows tools and document-management systems ask for that specific spelling, and renaming a file after the fact is exactly the sort of thing that gets a submission rejected.

How to Convert EPS to JFIF

1. Upload Your EPS File: Drag the .eps onto the page or click "+ Add Files". Several files can be queued and all of them render with the same settings. An EPS with a large embedded raster can be surprisingly big on disk, since PostScript often stores image data as uncompressed ASCII hex.
2. Pick a Quality Preset: Under Image Compression, Quality Preset runs from Highest through Very High (Recommended), High, Medium, Low, Very Low to Lowest. Each rung is a fixed JPEG quality value — see the ladder below.
3. Set the Output Size Under Image resolution: This is the control that matters most here. Keep original is selected and gives you one pixel per point of the EPS bounding box. Preset Resolutions, Resolution Percentage, Width, Height and Width x Height are all available if that is not the size you need. There is also a Specific file size mode under Image Compression, which takes a target in bytes, kilobytes or megabytes — the input starts at 8 MB — with an Auto Scale toggle that lets the converter reduce dimensions as well as quality to reach it.
4. Convert and Download: Click Convert and save the .jfif. Files upload over an encrypted connection, are rendered and compressed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.

The Size You Get, and Why

The PostScript is rasterised at its declared bounding box with one pixel per point — effectively 72 dpi. A logo whose bounding box reads 0 0 200 100 renders as a 200 x 100 pixel image; we measured exactly that. An EPS produced by wrapping a raster (the way this site's own EPS output works, at 1 px = 1 pt) round-trips back to the pixel dimensions it started with, so an 800 x 600 source came back as an 800 x 600 JFIF.

There is no DPI or density control on this page, and asking for a larger output under Image resolution does not re-run the PostScript at a higher resolution — it resamples the 72-dpi render. We checked this directly: asking for 800 x 400 from a 200 x 100-point EPS produced an image within 1.7% RMSE of simply enlarging the 200 x 100 render four times, and nowhere near a genuine high-resolution rasterisation of the same file. For crisp large output from vector artwork, scale the geometry in a vector editor (or enlarge the bounding box) before converting.

Two more render behaviours worth knowing:

• Unpainted area comes out white. PostScript has no alpha model, but artwork frequently paints only part of its bounding box — a logo with clear space around it. Those regions arrive as transparency from the renderer and are flattened onto white on the way into the JPEG, so you get a white rectangle rather than a black one.
• Fonts that were not embedded get substituted. An EPS that merely names a typeface relies on the renderer having it. Ours does not have your foundry's licensed fonts, so text set that way is drawn with a substitute and the metrics shift. Convert text to outlines in the originating application if the lettering has to be exact.

Flat vector artwork is the worst case for JPEG: hard edges between solid colours produce ringing that the format handles badly. If the EPS is a logo or a line drawing rather than a photograph, either stay at Highest or use a lossless target — EPS to PNG is the better fit for that kind of art.

Frequently Asked Questions

Is a .jfif file different from a .jpg?

Not in any way that affects the pixels. Both hold a JPEG datastream, and every decoder written since the 1990s reads either. JFIF is the interchange convention that pinned down the things the original JPEG standard left open — component order, aspect ratio signalling, resolution units — and .jfif is one of the extensions used for it. Choose it when a system explicitly asks for .jfif; otherwise .jpg is the more conventional name and EPS to JPG produces it.

Why is my converted logo so small?

Because its bounding box is small. Vector artwork carries no resolution — the EPS declares its extent in points, and this converter maps one point to one pixel. A business-card logo might legitimately declare a 180 x 60-point box, which becomes a 180 x 60 pixel image. Set an explicit Width x Height to get the size you want, but be aware you are enlarging a 72-dpi render rather than re-rendering; for a genuinely sharp result, enlarge the artwork in a vector editor first.

Can I get a 300 dpi version for print?

Not directly, and this is worth saying plainly: there is no DPI control on this page, and JPEG is the wrong end point for print artwork anyway. Requesting large pixel dimensions upsamples the 72-dpi render. If the destination is a printer, keep the artwork in vector form — EPS to PDF wraps the same PostScript geometry in a container that opens everywhere, with no rasterisation step at all.

Does the conversion trace or vectorise anything?

No — it goes the other way. Rasterising is one-directional: the paths, text and colour definitions in the PostScript are executed once and the result is a grid of pixels. Nothing in the JFIF remembers that a shape was ever a curve. Keep the .eps if you may need to edit the artwork again.

What happens to CMYK or spot colours?

They are converted to RGB for the JPEG, because JPEG in practice is an 8-bit-per-channel RGB format and JFIF assumes it. Prepress files built around specific spot inks will shift, sometimes noticeably in saturated areas, because a spot colour has no exact RGB equivalent. That is unavoidable for any raster target — plan for it, and do critical colour work in the prepress application.

My EPS has a preview image embedded. Which one gets used?

The PostScript, not the preview. Many EPS files carry a low-resolution TIFF or WMF preview so that page-layout applications can show something without running a PostScript interpreter. Those previews are typically coarse and are only a placeholder; this conversion executes the actual PostScript, which is why the output matches the artwork rather than the thumbnail your layout program displayed.

Why does my white artwork disappear?

Because unpainted bounding-box area flattens to white, so white-on-transparent artwork lands as white-on-white. This is the single most common surprise with logos supplied as "knockout" or reverse versions. Place the artwork on a coloured background in the originating application before converting, or convert to a format that keeps transparency — EPS to PNG preserves it.

Can I hit an exact file size?

Yes. Switch from Quality Preset to Specific file size under Image Compression and type a target in bytes, kilobytes or megabytes; the input opens at 8 MB. The converter then searches for the JPEG quality that lands near your number instead of you working backwards from a preset. Leave Auto Scale on to allow pixel dimensions to shrink as well when compression alone cannot reach the target.

Why did my EPS fail to convert?

Two causes cover most of it. The first is a file that is not really EPS: a .ps page description, a PDF with the wrong extension, or an Illustrator native file saved without PostScript compatibility. The second is a truncated or corrupt PostScript program, which the renderer cannot complete. Re-export from the originating application, and if the file is genuinely a PostScript page rather than encapsulated artwork, convert it as PostScript instead.

What happens to my file after conversion?

It is uploaded over an encrypted connection, rendered and compressed on our servers, and both the upload and the output are deleted automatically after a few hours. There is no sign-up and no watermark, and nothing is shared or made public. If you need to shrink the finished JPEG further afterwards, Compress JPEG works on it directly.
